Plant adaptation, for Some plants?

Answer 19

— have fibrous, thick mat of roots to gather water near upper layers of soil.
— have long taproot that collect water that is deep in the soil.

Question 20

Plant adaptation, for Wild mustard?

— have adapted to produce seeds in a short growing season.

Question 21

Three main nutrients for a plant are?

Answer 21

Potassium, nitrogen, calcium

Question 22

Nitrogen is?

Answer 22

Lack of nitrogen leads to yellow leaves

Question 22

Plants provide fibre (fiber, cotton fiber, Plant fiber)

Answer 22

— Fibres, in some plants it is used to make cloths.

— Cotton fibre, is used in shirts and jeans.

— Plant fibre, is used to make paper and paper products.

Answer 24

— Crumbly, like a moist cake.
— Dark brown or black collaring.
— Balance between organic particles and minerals.
— Absorbs lots of water, and can stay moist for a
long time.
— Lots of nutrients, and is great for plants to grow.

Question 25

Clay soil?

Answer 25

— Feels slippery when moist.
— Sticks together and can form a tight ball.
— Dry clay is very hard.
— Colour can vary.
— Lots of very small minerals, and little humus.

— Can hold lots of water, but little space for air.

Question 26

Sandy soil?

Answer 26

— Is light brown
— Does not form clumps
— Mostly minerals, very little humus
— Dries quickly because water runs through it very fast.
