Plant Biology

Question 0

Palisade mesophyll means

Answer 0

Most photosynthesis occurs here, cells all packed with full of chloroplasts.

Question 1

Epidermis means

Answer 1

Protects leaf, stops bacteria and viruses entering the leaf

Question 2

Spongy mesophyll means

Answer 2

Some photosynthesis occurs here, less chloroplasts than palisade, allows easy movement of gases

Question 3

Vein means

Answer 3

Carries water in xylem and food in phloem

Question 4

Guard cells mean

Answer 4

Increase and decrease in size to control the size of the stomata

Question 5

Stomata means

Answer 5

Small pores, allow gases in and out of the leaf and how water is lost from the leaf. There are more stomata on the lower side of the leaf.

Question 6

Germination means

Answer 6

Breaking open the seed coat and the development of the stem and root.

Question 7

What do root hair cells do

Answer 7

Create a huge surface area for water and mineral absorption.

Question 8

Photosynthesis is

Answer 8

How green plants make their own food (glucose) by using Carbon dioxide and water.

Question 9

What is the word equation for photosynthesis?

Answer 9

Light
Carbon Dioxide + Water —> Glucose + Oxygen
Chlorophyll

Question 10

What is Hydrogen Carbonate Indicator used for?

Answer 10

To detect the levels of Carbon Dioxide.

Question 11

What do plants need water for?

Answer 11

To hold them up (support them) and for photosynthesis

Question 12

Transpiration is

Answer 12

Evaporation of water out through the stomata.

Question 13

What does the plant need Stomata for?

Answer 13

To allow the gases carbon dioxide and oxygen in and out.

Question 14

What do the guard cells do?

Answer 14

Open and close the stomata

Question 15

What are the environmental conditions needed for germination?

Answer 15

oxygen
moisture
heat

Question 16

what are the environmental conditions need for healthy seed growth?

Answer 16

oxygen
moisture
heat
light

Question 17

what are the advantages of leaves?

Answer 17

large surface area to absorb sunlight for photosynthesis

Question 18

what are the advantages of the stem?

Answer 18

transports water and minerals up the plant to the leaves and sugars (made in photosynthesis) up and down the plant

Question 19

what are the advantages of roots?

Answer 19

large surface area (root hair cells) to absorb minerals and water from the soil.

Question 20

plants need calcium to

Answer 20

produce new cell walls

Question 21

plants need magnesium to

Answer 21

to make chlorophyll

Question 22

plants need nitrogen ( in the form of nitrates) to

Answer 22

produce protein for growth

Question 23

where are most stomata found

Answer 23

on the underside of the leaf

Question 24

germination is

Answer 24

Breaking open the seed coat and the development of the stem and root.

Question 25

Root hair cells

Answer 25

Create a huge surface area for water and mineral absorption.

Question 26

Photosynthesis

Answer 26

This is how green plants make their own food (glucose) by using Carbon dioxide and water.
