Flashcards in Plant and animal cells Deck (13):
1

5 parts of a cell that both plants and animals have:

Nucleus
Cell Membrane
Cytoplasm
Mitochondria
Ribosomes

2

3 things that plant cells have but animal cells dont:

Choloroplast
Cell Wall
Vacoule

3

Palisade leaf cells and how they are adapted for photosynthesis

Lots of chloroplasts at top = close to light
Tall = Big surface area, absorbs Co2
Thin = Pack lots of cells at op of leaf

4

Factors that affect the rate of photosynthesis

Sunlight
Co2
Temperature

5

What happens to enzymes if the temperature gets too high?

If temperature gets too high, enzymes become damaged/denatured

6

Ideal farming conditions:

Green house :
Traps suns heat
Artificial light = more photosynthesis
Paraffin heater = increases Co2
Free from pests and disease
Fertilisers= improves soil (healthy growth)

7

What happens at a Mesophyll tissue? (plants)

Photosynthesis occurs

8

What happens at a xylem/phloem tissue? (plants)

Transportation of water, mineral ions and sucrose

9

What does a Epidermal tissue do? (Plants)

Covers whole plant

10

Give an example of a plant organ and its job:

Chloroplast contains Chorophyll = absorbs sunlight and converts Co2 and Water to Glucose and Oxygen

11

Equation for photosynthesis...

Co2 + H2O (sunlight)= Glucose + O2

12

Where is genetic material found in bacteria cells?

Cytoplasm

13

Where is genetic information in Animal cells found?

Nucleus
