Things i cant remember from mocks

whats the function of a nerve cell

to carry electrical impulses around the body

whats the function of a root hair cell

absorb mineral ions and water from the soil

whats the function of a palisade cell

to enable photosynthesis in the leaf

what are the adaptation of a muscle cell

contain protein fibres which can contract make cells shorter, contains lots of mitochondria to release energy from respiration, allowing muscles to contract

what are the adaptation of a nerve cell

branched ending called dendrites to make connections with other neurones or effectors, myelein sheath insulates the axon to increase the transmission speed of the electrical impulses

what are the adaptation of a root hair cell

long production speeds up the absorption of water and mineral ions by increasing the surface area of the cell, lots of mitochondria to release energy for the active transport of mineral ions from the soil

what are the adaptation of a palisade cell

lots of chloroplasts containing chlorophyll to absorb light energy, located a the top surface of the leaf where it can absorb the most light energy

whats the differences between an electron and light microscope

an electron microscope uses a beam of electrons to form images, samples cant be living, they have high magnification and resolution and it expensive. a light microscope uses light to form images, can view living samples, have low magnification and resolution and are relatively cheap

What is an example of active transport

Minerals into root hair cells

What is an example of osmosis

Water into root hair cells

What’s an example of diffusion

Oxygen from blood to alveoli

What’s an atom

The smallest part of an element

What is high pressure

When cool air descends

What is low pressure

When warm air ascends
