Answer 1

Anchor the plants
Absorb the water
And mineral ion (it has nitrates in it )

Question 2

What do leaves do

Answer 2

Carry out photosynthesis

Question 3

How do plays get there energy

Answer 3

From the sun

Question 4

Equation for photosynthesis

Answer 4

Co2+ h20- c6 h12 06 + 02

Question 5

Why do plants need water

Answer 5

To make glucose because of the water reacts with carbon dioxide to make glue cose

Question 6

Why do plants need nitrates

Answer 6

To make protein because of the nitrogen in the nitrates

Question 7

Why do plants need magnesium

Answer 7

To do photosynthesis

Question 8

What happen to the leaves if there is no magnesium

Answer 8

It turn yellows

Question 9

All the organism of a plant

Answer 9

Stem
Leaves
Roots
Flower

Question 10

What is translocation

Answer 10

Moves dissolved sugars

Question 11

Give one use of sugars for plant

Answer 11

Respiration
.Glucose makes amino acid and proteins
Glucose can be stored in starch
Glucose makes fat and oils
Glucose makes cellulose

Question 12

What is cellulose

Answer 12

Used to make cell wall

Question 13

Palisade cell

Answer 13

Does photosynthesis because they have lot of chlorophyll

Question 14

Sponge mesophyll do

Answer 14

They have air spaces so they can speed up the diffusion for carbo dioxide to go to the palisade

Question 15

What does guard cell do

Answer 15

Open and close the stomata so they keep the water in the plant so they can survive

Question 16

What is the leaf vein

Answer 16

They have pipes called xylem and phloem xylem is to transport the water and phloem takes the glucose way from the plants so they can take to other parts of a plant

Question 17

Meristem cell

Answer 17

A area that contain stem cells

Question 18

What is taking cutting

Answer 18

Cutting meristem cells so the thing that has just been cut can grow and make a new plant because of the stem

Question 19

What do stem cell do in plants

Answer 19

They are found in the meristem
The stem cells are able to produce clones of the plant

Question 20

What is Multi cellular

Answer 20

Organisms that have a large surface are to the volume ratio so that all substance can be exchanged

Question 21

Where is gas exchange found in humans

Answer 21

Lungs but the alveoli is where gas exchange takes place they have large surface area most lining thin wall and a good blood supply

Question 22

What are villi

Answer 22

It is the small intestine and it increases the are to asorb more digested food

Question 23

How does exchange in fish work

Answer 23

They have a large surface area for gas exchange which are gills . The water is transported to the blood by diffusion.
The gill has a gill filament which give a bigger surface area .lamella coves the filament to increase the surface area.

Question 24

Leaves main purpose

Answer 24

To absorb energy for photosynthesis

Question 25

What’s a phloem

Answer 25

Transports sugars around the plant
