What are root hair cells? Where is it located? What does it do?

Cells that take up water. it is located in the roots. It absorbs H2O and minerals from the soil and it is transported into the ylem vessels

What is an adaptation of root hair cells?

They provide a large surface area to maximise amount of H2O taken up.

What are root hairs?

A part of root hair cell that touches the soil.

KIRTIESH REMEMBER IN EXAMS IF THEY ASK WHICH PART OF THE ROOT TAKES UP WATER, YOU SAY ROOT HAIR CELL NOT ROOT HAIR BECAUSE RHC IS BETTER.

OKAY BRO!

What is the process in which H2O and minerals are absorbed to RHC?

Osmosis

The process in which water moves from a place with high concentration to a place with low concentration.

WHAT PROCESS IS THIS?

OSMOSIS!

What are xylem vessels?

Vessels that transport H2O and minerals to the leaf from the root hair cells.

How does water travel from the soil to the leaf?

Soil -> Root hair cells -> xylem vessels -> Leaf ->

What is the root cap?

A structure that protects the tip of the root.

What happens when water reaches the leaf?

Water reaches the leaf via the xylem vessels. Then, it enters the cell, where some of it is used for photosynthesis. most of it isn't used, so it soaks in the cell wall and evaporates to ebcome water vapour. Then, it diffuses through the air spaces and out of the stomata.

Why is transpiration important for cooling?

When water in the leaf evaporates to become water vapour, it causes a cooling effect.

Why is transpiration important for structure?

It provides water for cells to become turgid.

Why is transpiration important for photosynthesis?

It provides water for photosynthesis.

Why is transpiration important for transportation?

The water can transport mineral ions

Why is water important for cooling?

When it evaporates, it causes a cooling effect. This allows the plant to stay cool, especially if it is found in hot places.

Why is water important for structure?

It helps them to stand upwright and not wilt.

Why si water important for transportation?

The water can transport the dissolved mineral ions

Why is water imporatnt for photosynthesis?

It is needed to make glucose and oxygen.

What is excretion

The process of removing waste products from the body

Which system is responsible for this process?

Urinary system, renal system or excretory system

What are the kidneys for?

Filter blood to seperate it with urea. Then it produces urea with excess water.

What are the ureters for?

To transport the urine to the bladder, where it is stored.

What is the bladder for?

To store urine until it is full.

What happens when the bladder is full?

It sends signals to the body to use the bathroom.

What is the urethra for?

To transport the urine out of the body.

What is the pathway for the excretory system?

Kidneys -> Ureter -> Baldder -> Urethra ->

How does the nutrients fromt he mother go to the fetus?

Nutrients from the mother's blood diffuses to tfhe fetus's blood.

Why does a fetus need protein?

To produce new cells for the fetus's growth.

WHy does a fetus need carbohydrates?

To supply it with energy

WHy does a fetus need iron?

To rpoduce haemoglobin to transport oxygen

Why does a fetus need calcium?

To make strong boens and teeth

What harmful chemicals can the mother give the fetus if she smokes?

Carbon monixide and nicontine

Why is nicontine bad for fetus?

It damages blood vessels

Why is carbon monoxide bad for fetus?

It reducecs the amount of haemoglobin, therefore reducign the amount of oxygen.
