Plants are living things Flashcards
Plants have lots of jobs, such as providing animals with food and releasing oxygen into the air. To survive and carry out these jobs, they all need three important parts:
roots
leaves
stem
What is the job of the roots?
Take up water and
nutrients
from the soil. The roots also keep the plant steady and upright in the soil.
What is the job of the Leaves ?
Use light from the Sun, along with
carbon dioxide
from the air and water to make food for the plant. This process is called photosynthesis.
What is the job of the stem?
Carries water and nutrients to different parts of the plant. The stem of a tree is called its trunk. This often divides into smaller branches.
What is the job of the Flowers ?
Are involved in plant reproduction and produce seeds from which new plants grow.
What things do all plants need?
air
light
water
nutrients
the right temperature
Sunflowers need lots of ?
Sunlight
Flowers that grow in woodlands need a lot less?
Sunlight
Cacti can live off a small amount of?
Water
Pine trees can grow in places where it is much?
Colder
Olive trees have adapted to live in?
Hot weather
Mangrove plants need lots of ?
Water
What will happen if a plant do not get the right amount of sun?
They won’t get the right amount of nutrients. Unhealthy plants turn brown and
wilt
.
How can we can spot healthy plants?
They normally stand upright and are green.
.
How do plants make their own food?
.
They make their own food in their leaves by
photosynthesis.
.
What is photosynthesis?
The process in which plants use sunlight, water and carbon dioxide to create their own food and oxygen.
What is the meaning of nutrients?
NUTRIENT
A substance needed by an organism to stay alive and healthy. For example, carbohydrates, proteins and lipids.
What does it means when a plant wilts?
WILT
When a part of a plant is exposed to lots of heat or loses water so it droops and withers.
The leaves of a plant use ___ to make food.
sunlight
What two things do the roots absorb that a plant needs?
Water and nutrients
What happen when plants make their own food?
Photosynthesis
What is the first stage in the life cycle of a plant?
Roots
How do plants make food?
Plants need water to make their own food. This is called photosynthesis. It happens in plant leaves. Plants also need carbon dioxide from air and sunlight to make their food.
What else is needed for photosynthesis besides water?
Carbon dioxide
Which part of the plant carries water upwards?
Stem
What do roots have on their outside to help absorb water?
Hairs
Why are plants important?
They provide us with food and they even help us to breathe.
Which part of a plant absorbs water?
Roots
What happens during photosynthesis?
They release oxygen from their leaves. This gas is needed by all living things. So without plants, many other organisms would not be alive. They also take in carbon dioxide from the air during photosynthesis.
What is Photosynthesis?
A chemical reaction that takes place in plants. Plants turn carbon dioxide and water into glucose, their main source of energy, and oxygen. Sunlight provides the energy needed for photosynthesis to take place.
What is reproduction?
Reproduction means to have babies or offspring. Just like animals, plants need to be able to reproduce. The offspring of plants are called seeds or bulbs.
What is is pollination?
Pollen is moved from one flower to another by the wind or by insects like bees. This is pollination.
What is fertilization?
When pollen reaches the new flower, it travels to the ovary where it joins with egg cells (ovules) to make seeds. This is fertilization – just like in animals.
What is dispersal?
The seeds are scattered by animals or the wind. This process is called dispersal.
What is germinate?
Some of the seeds will germinate and grow into new plants.
What are the offspring of plants are called?
Seeds or bulbs.
Reproduction means?
To have babies or offspring
flowers have both ……… parts and ……. parts.
Male and Female
………..are involved in the reproduction of many plants
Bees
What is Asexual reproduction?
Some plants can also reproduce without an egg cell being fertilised to produce a seed. Instead, these plants produce an identical copy of themselves. This type of reproduction is known as asexual reproduction.
Plants can reproduce asexually in a number of different ways. Name them.
Some plants produce bulbs, like daffodils and snowdrops. Others, like potatoes, produce tubers. These sit under the soil and develop into new plants the next year.
Lots of plants rely on insects like bees to?
Reproduce
To make a seed, a flower needs to be?
Pollinated
What happens when pollen has moved from one flower to another?
The flower that loses pollen will start to die. It no longer needs its colourful petals, scent or nectar. But before it dies, the flower will produce seeds.
How do flowers encourage bees to visit them?
Flowers have colourful petals and an attractive scent. Some flowers give the bees a sugary reward called nectar too.
Plants spread their seeds in lots of different ways. This is called?
dispersal
Plants growing near a river or the sea may use the ………….. to transport their seeds.
Flowing Water
Many plants also use animals to carry their seeds. This type of seed may have handy hooks which attach to an animal’s ……..
Fur
The plants might make tasty fruit to enclose the seeds, which attract animals to eat them. The seeds pass out in the animal’s………. and grow into new plants.
Poo
Some seeds are transported by the wind and are shaped to? float, glide or spin through the air.
Float, glide or spin through the air.
However a seed is spread, it will …………… and grow into a new plant when the conditions are right.
Germinate
How do most flowering plants reproduce?
Making seeds
Why do some plants with flowers need insects like bees to help them make seeds?
To carry pollen
To make a seed, a flower needs to be _____.
Pollinated
