Science Exam- Plants

Question 0

What happens during photosynthesis?

Answer 0

Plants take in 3 different things for photosynthesis
Sunlight CO2 and Water. They need those things.
They take sunlight and CO2 through their leaves through little holes called stomata. Chlorophyll captures the CO2 and sunlight which create Glucose and oxygen.

Question 1

What is photosynthesis?

Answer 1

Photosynthesis is the process of plants creating their own nutrition

Question 2

What does a plant do with glucose and oxygen

Answer 2

Plants get rid of oxygen since it is a waste product to them

Plants use glucose in produce energy

• Grow
• Reproduce
• Heal

Question 3

How does the plants absorb water?

Answer 3

Through osmosis, it is the movement from a high concentration to a low concentration through a semi-pemable membrane
Osmosis occurs through the roots and stem

Question 4

How does osmosis keep a low concentration

Answer 4

Water is transported from and through the roots to the rest of the plant via the xylem

Question 5

What are the functions of roots

Answer 5

Absorption- To absorb water and minerals from the soil
Anchorage- To stabilise the plant and stop it from falling over
Transport- To move water to the rest of the plant

Question 6

What is the process water and nutrients go through the root cells

Answer 6

Water and minerals are taken in by root hairs
They are passed from cell to cell
In the stem water is transported to the rest of the plant via Xylem
Minerals, water, and glucose is transported by phloem

Question 7

What is the equation for photosynthesis

Answer 7

CO2 + H2O Sunlight –> Chlorophyll C6H6O6 + 6O2

Question 8

What is in a animal cell

Answer 8

Nucleus- Contains DNA and controls cell
Cytoplasm- helps fill the cell and keeps things in place
Cell membrane- Keeps cell together and controls what goes in and out
Golgi body- Makes protein
Mitochondria- Controls respiration and makes energy

Question 9

What is in a plant cell

Answer 9

Nucleus- Contains DNA and controls cell
Cell membrane- Keeps cell together and controls what goes in and out
Mitochondria- Controls respiration and makes energy
Vacuole- Holds materials and wastes, provides structure and support for growing plants
Cell Wall- Acts as a skeleton for plants and keeps things together
Chloroplasts- Work to convert sunlight into glucose
