Worksheet time: 25mins
Which chemical reaction takes place in plant cells during the day?
Respiration
Photosynthesis
Digestion
Mitosis
How do plants obtain their energy at night?
From the air
From the stars
Through cellular respiration
From the Moon
Photosynthesis is:
carbon dioxide + (a) --------> glucose + oxygen
In which plant cell organelle does photosynthesis take place?
The nucleus
The cytoplasm
Mitochondria
Chloroplasts
The reactants involved in photosynthesis are...
carbon dioxide and glucose
water and oxygen
carbon dioxide and water
water and glucose
What is this plant deficient in?
Potassium
Nitrate
Phosphorous
Iron
What does phosphorous deficiency in plants lead to?
Yellow leaves
Poor root growth
Abnormally shaped leaves
Reduced plant size
Nitrogen absorbed by the roots from the soil helps plants synthesize chlorophyll and (a) .
What do xylem vessels transport in plants?
Water and mineral salts
Water
Sucrose
Mineral salts
What do phloem vessels transport in plants?
Sucrose
Water
Mineral salts
Carbon dioxide
Identify the red vessels in this cross-section of a plant stem
Phloem
Roots
Palisade mesophyll
Xylem
What is the function of the palisade mesophyll tissue?
Enable gas exchange to take place
Facilitate photosynthesis
Protect the leaf
Allow Oxygen to escape the leaf
What is the primary function of spongy mesophyll cells?
Give the leaf its structure
Retain water in the leaf
To facilitate the movement of carbon dioxide and oxygen into and out of the leaf
Keep the leaf cool
How are leaf palisade cells adapted for their function?
The are big
They are near the upper leaf surface and contain a large number of chloroplasts needed for photosynthesis
They have lots of vacuoles
They can move inside the leaf
The part of the flower labelled 10 is the (a) .
The part of the flower labelled 4 is the (a) .
The part of the flower labelled 7 is the ______.
Anther
Stamen
Filament
Ovule
Some flowers have brightly coloured petals and are scented to attract (a) such as bees and hummingbirds.
When the pollen from a flower is deposited on the stigma of the same flower, this is know as:
Symbiosis
Independent pollination
Self-pollination
Cross-pollination
This flower is pollinated by:
Insects
Pollinators
Fruit bats
The wind
Pollination in plants is the process by which:
Pollen grains from the male anther of a flower are deposited on the petals.
Pollen grains from the male anther of a flower are deposited on the female stigma.
The germinating of a new plant from a seed.
Pollen grains from the male anther of a flower are deposited on the stamen.
During fertilization in flowers, the pollen grain on the stigma will grow a pollen tube which will carry the male (a) down towards the ovule in the ovary.
Why are fruits brightly coloured, sweet, and scented?
To scare animals away
To look attractive to pollinators
So that they can be more expensive in supermarkets
To encourage animals to eat them and disperse their seeds through defecation later on.
This is an example of seed dispersal by:
Water
Bursting
Wind
Animals
This plant disperses its seeds by:
Wind
Bursting
Water
Soil
