Bindweed grows as high as possible on the rose bush so that the bindweedcan get as much .................................... as possible. |
Sunlight |
|
Bindweed grows around the rose bush because the rose bush provides....................................... for the bindweed. |
Support |
|
A gardener cut through the stem of the bindweed at X.Two days later the bindweed above X was dead.Why did the bindweed die? |
No water |
|
The gardener adds fertiliser to the soil to help her rose bushes to grow well.What do plants get from the fertiliser? |
Minerals |
|
Plant roots have root hairs.Which diagram shows a root hair? |
Diagram C shows a root hair |
|
Photosynthesis equation (word form) |
Water + Carbon dioxide => glucose + oxygen |
|
Photosynthesis equation (Scientific form) |
H20 + CO2 => C6 H12 06 + O2 |
|
Plants in shady areas have bigger leaves. Why is that? |
To absorb as much light as possible |
|
What part of the leaf cells makes the leaf green? |
Chloroplasts |
|
Cell wall = ? Cytoplasm = ? Nucleus = ? Vacuole = ? |
Cell wall = D Cytoplasm = F Nucleus = A Vacuole = C |
|
Which of the labelled parts are also present in an animal cell? |
Nucleus, Cytoplasm |
|
Cell X is found = ? Cell Y is found = ? |
Cell X = Leaf Cell Y = Root |
|
Give the name of part B. |
Cell wall |
|
Give the letter which labels the nucleus. |
A |
|
What is the function of the nucleus? |
to control the cell, contains genetic information, controls the production of enzymes |
|
How can you tell from the diagram that photosynthesis cannot take placein cell Y? |
There are no chloroplasts |
|
Which process takes place in both cell X and cell Y? |
Respiration |
|
What is the mass of a tree made up of? |
Carbon |
|
How can it be proven that the mass of a tree is made up of carbon? |
The act of photosynthesis consists of splitting C02 into oxygen and carbon. The oxygen is released but the carbon is not therefore the carbon makes up most of the mass. |
|
Give two reasons why photosynthesis occurs most rapidly in the summer |
It is warmer during summer There is more sunlight for the plant to absorb |
|
Name the two substances produced in photosynthesis |
Glucose and Oxygen |
|
Trees which lose all their leaves in the autumn are described as deciduous.How can you tell from graph A that the tree being investigated is deciduous? |
Carbon dioxide uptake stops in autumn |
|
What is the name of the process in the tree which produces carbon dioxide? |
Respiration |
|
In which part of a plant would you find this type of cell? |
The leaf |
|
Give the function of the chloroplasts |
Absorb sunlight |
|
Give the function of the cell wall |
To support and protect the cell |
|
Give the names of two labelled parts that are not present in animal cells. |
Chloroplast and Vacuole |
|
Photosynthesis or for respiration |
