Q

What is the first sign of a seed sprouting?

A

The hypocotyl appears as the seed swells and bursts.

Hypocotyl = First Hope.

24
Q

Why are seeds light and feathery in some plants?

A

To aid in wind dispersal.

Feathered Seeds Fly.

25
Q

Why do some plants have thorns on their stems?

A

To protect against predators.

Thorns = Tough Guards.

26
Q

How do broad leaves like those of aloe benefit plants?

A

They store water for use in dry conditions.

Broad Leaves = Water Banks.

27
Q

Why are some fruits smooth and thin-skinned?

A

To be easily eaten and digested by animals, aiding seed dispersal.

Thin Skin Travels.

28
Q

Why do soft-stemmed plants grow better from cuttings?

A

They root more easily than plants with hard stems.

Soft Stems, Easy Growth.

29
Q

What are the key conditions for a cutting to grow roots?

A

Water, warmth, and sunlight.

Water + Warmth = Roots.

30
Q

How can you test if something is living or non-living?

A

Check if it performs the seven life processes: grow, reproduce, feed, move, breathe, excrete, sense.

GRaF Me BE Sense.

31
Q

Why do some living things appear non-living temporarily?

A

They may require specific conditions to show life, e.g., seeds needing water and warmth to grow.

Life Needs Activation.

32
Q

Why do plants have different types of roots?

A

To adapt to their environment, e.g., big trees have strong roots for anchoring, while smaller plants may have thinner roots.

Roots Reflect Needs.

33
Q

What are the functions of fruits in plants?

A

Fruits develop from flowers and contain seeds, aiding in plant reproduction.

Fruits Form Future Plants.

34
Q

How do thick stems benefit plants in arid regions?

A

They store water, helping the plant survive dry conditions.

Thick Stems, Water Stores.

35
Q

Why do some flowers have dull colors?

A

To avoid attracting animals, which is common in grasses.

Dull Flowers, No Pollinators.

36
Q

How do thorny stems protect plants?

A

They deter animals from eating the plant.

Thorns = Tough Protection.

37
Q

What conditions are necessary for germination?

A

Warmth, light, water, and air.

WLWA for Growth.

38
Q

What happens to a seed coat during germination?

A

It splits open to allow the seedling to emerge.

Seed Coat Splits, Life Begins.

39
Q

Why is oxygen important for germination?

A

It supports the energy required for the seed to grow.

Oxygen = Germination Fuel.

40
Q

What parts of a seedling emerge first?

A

The root (radicle) and then the shoot.

Root First, Shoot Follows.

41
Q

What happens if a plant gets too much or too little warmth?

A

It struggles to grow or becomes stunted.

Warmth Balance = Growth.

42
Q

Why do plants need strong stems?

A

To support leaves and flowers for photosynthesis and reproduction.

Strong Stem, Strong Plant.

43
Q

How do thin-skinned fruits aid in seed dispersal?

A

Animals eat the fruits, digest the flesh, and disperse the seeds.

44
Q

How do broad leaves help plants in wet climates?

A

They collect more sunlight for photosynthesis.

Broad Leaves, More Light.

Q

What is an example of a non-living thing that used to be alive?

A

Wood that has burned in a fire.

Q

Why do living things need to excrete waste?

A

To remove harmful substances and maintain balance.

Q

How do stems contribute to photosynthesis indirectly?

A

They support leaves, allowing them to access sunlight.

48
Q

Why are seeds important for plants?

A

They enable reproduction and growth of new plants.

Seeds = Next Generation.

49
Q

How do plants with thorns survive better in their environment?

A

Thorns deter herbivores from eating them.

Thorns = Armor.

50
Q

Why do some plants have thick, waxy leaves?

A

To reduce water loss and store moisture.

51
Q

What happens if a plant does not get enough air?

A

It cannot make food through photosynthesis and will die.

No Air, No Food.

52
Q

Why is warmth crucial for seed germination?

A

It activates enzymes needed for growth.

Warmth Wakes Seeds.

53
Q

How do bright flowers increase a plant’s chances of reproducing?

A

They attract pollinators like bees, which transfer pollen.

Bright Colors Bring Bees.

54
Q

What is pollination?

A

The transfer of pollen from one flower to another to allow fertilization.

Pollination = Pollen Sharing.

55
Q

Why do some fruits have hooks or spines?

A

To stick to animals and disperse seeds.
