Plant 3 Flashcards
What are the seven life processes of living things?
Growing, reproducing, feeding, moving, breathing, excreting, sensing.
GRaF Me BE Sense (Growing, Reproducing, Feeding, Moving, Breathing, Excreting, Sensing)
What differentiates living things from non-living things?
Living things carry out all seven life processes; non-living things do not.
7 Processes = Life
Give an example of a non-living thing that can appear alive under certain conditions.
Yeast, which starts bubbling when given sugar and heat.
Yeast ‘wakes up’ with sugar and heat
What are the four main parts of a plant and their functions?
Roots: Anchor and absorb, Stem: Support and carry, Leaves: Make food via photosynthesis, Flowers: Attract pollinators and reproduce
RSFL - Roots Stay Firm, Leaves Flower (Roots, Stem, Leaves, Flowers)
What part of the plant helps store water and grow in arid areas?
Leaves, like those of aloe, which are thick and store water.
Aloe’s Leaves = Water Tanks
What four things do plants need to grow?
Water, light, warmth, and air.
Plants WLWA (Water, Light, Warmth, Air)
What happens if a plant doesn’t get enough water?
The stems weaken, and the leaves become dry and small.
Dry Water = Dry Plant
Why is light important for plants?
It helps in photosynthesis, which is necessary for growth.
Light = Life (Photosynthesis)
What is germination?
The process where a seed sprouts and grows into a plant.
Germination = Growth Start
What is required for a seed to germinate?
Warmth, light, and water.
Warm Light Water (WLW)
How can new plants grow from cuttings?
A leaf and stem cutting placed in water and warmth will grow roots and can develop into a new plant.
Cut + Water = Root (New Plant)
How do thick, prickly fruit skins benefit a plant?
They protect the plant against predators.
Thick Skin = Tough Defense
Why do some plants have feathery seeds?
To aid in easy dispersal by wind.
Feathers Fly (Seeds Disperse)
What is the benefit of colorful flowers to plants?
They attract pollinators like bees and birds.
Bright Flowers = Buzz Bees
What is an example of a living thing that seems dead but can be revived?
Seeds that are planted and grow.
Sleeping Seeds Wake Up.
Why do non-living things like wood burn in a fire?
They used to be living but are now dead.
Living -> Dead -> Burn.
How do roots help plants survive?
They anchor the plant and absorb water and minerals.
Roots Reach for Resources.
What is the function of the stem in plants?
It keeps the plant upright and supports leaves, flowers, and fruits.
Stem Stands Strong.
How do flowers help plants reproduce?
They attract insects and birds for pollination.
Flowers Fly Pollination.
What happens to leaves if a plant doesn’t get enough light?
The leaves become pale and die.
No Light = No Life in Leaves.
What is the role of air in plant growth?
Oxygen in the air is used by green leaves to make food.
Oxygen = Energy.
What is a seedling?
A new plant that grows from a seed.
Seedling = Small Plant.
What is the first sign of a seed sprouting?
The hypocotyl appears as the seed swells and bursts.
Hypocotyl = First Hope.
Why are seeds light and feathery in some plants?
To aid in wind dispersal.
Feathered Seeds Fly.
Why do some plants have thorns on their stems?
To protect against predators.
Thorns = Tough Guards.
How do broad leaves like those of aloe benefit plants?
They store water for use in dry conditions.
Broad Leaves = Water Banks.
Why are some fruits smooth and thin-skinned?
To be easily eaten and digested by animals, aiding seed dispersal.
Thin Skin Travels.
Why do soft-stemmed plants grow better from cuttings?
They root more easily than plants with hard stems.
Soft Stems, Easy Growth.
What are the key conditions for a cutting to grow roots?
Water, warmth, and sunlight.
Water + Warmth = Roots.
How can you test if something is living or non-living?
Check if it performs the seven life processes: grow, reproduce, feed, move, breathe, excrete, sense.
GRaF Me BE Sense.
Why do some living things appear non-living temporarily?
They may require specific conditions to show life, e.g., seeds needing water and warmth to grow.
Life Needs Activation.
Why do plants have different types of roots?
To adapt to their environment, e.g., big trees have strong roots for anchoring, while smaller plants may have thinner roots.
Roots Reflect Needs.
What are the functions of fruits in plants?
Fruits develop from flowers and contain seeds, aiding in plant reproduction.
Fruits Form Future Plants.
How do thick stems benefit plants in arid regions?
They store water, helping the plant survive dry conditions.
Thick Stems, Water Stores.
Why do some flowers have dull colors?
To avoid attracting animals, which is common in grasses.
Dull Flowers, No Pollinators.
How do thorny stems protect plants?
They deter animals from eating the plant.
Thorns = Tough Protection.
What conditions are necessary for germination?
Warmth, light, water, and air.
WLWA for Growth.
What happens to a seed coat during germination?
It splits open to allow the seedling to emerge.
Seed Coat Splits, Life Begins.
Why is oxygen important for germination?
It supports the energy required for the seed to grow.
Oxygen = Germination Fuel.
What parts of a seedling emerge first?
The root (radicle) and then the shoot.
Root First, Shoot Follows.
What happens if a plant gets too much or too little warmth?
It struggles to grow or becomes stunted.
Warmth Balance = Growth.
Why do plants need strong stems?
To support leaves and flowers for photosynthesis and reproduction.
Strong Stem, Strong Plant.
How do thin-skinned fruits aid in seed dispersal?
Animals eat the fruits, digest the flesh, and disperse the seeds.
Thin Skin Travels Far.
How do broad leaves help plants in wet climates?
They collect more sunlight for photosynthesis.
Broad Leaves, More Light.
What is an example of a non-living thing that used to be alive?
Wood that has burned in a fire.
Burned Wood = Once Alive.
Why do living things need to excrete waste?
To remove harmful substances and maintain balance.
Excretion = Clean Living.
How do stems contribute to photosynthesis indirectly?
They support leaves, allowing them to access sunlight.
Stems Lift Leaves to Light.
Why are seeds important for plants?
They enable reproduction and growth of new plants.
Seeds = Next Generation.
How do plants with thorns survive better in their environment?
Thorns deter herbivores from eating them.
Thorns = Armor.
Why do some plants have thick, waxy leaves?
To reduce water loss and store moisture.
Waxy Leaves Save Water.
What happens if a plant does not get enough air?
It cannot make food through photosynthesis and will die.
No Air, No Food.
Why is warmth crucial for seed germination?
It activates enzymes needed for growth.
Warmth Wakes Seeds.
How do bright flowers increase a plant’s chances of reproducing?
They attract pollinators like bees, which transfer pollen.
Bright Colors Bring Bees.
What is pollination?
The transfer of pollen from one flower to another to allow fertilization.
Pollination = Pollen Sharing.
Why do some fruits have hooks or spines?
To stick to animals and disperse seeds.
Hooks Hitch a Ride.
What are the benefits of wind dispersal for seeds?
It allows seeds to spread over a wide area for growth.
Wind Wings for Seeds.
