A subcellular structure made from cellulose fibres that strengthens the cell and supports the plant.

A subcellular structure that contains the green pigment chlorophyll, which absorbs light for photosynthesis.

A subcellular structure filled with cell sap that helps keep the cell turgid.

A chemical reaction that plants use to make glucose, taking place in the chloroplasts.

The net movement of particles from a low to high concentration, against a concentration gradient, using energy.

The size and scale of cells: the basics

Pupils will learn about biological molecules that are essential to life, including sugars and other carbohydrates, proteins and lipids, and the role of enzymes in catalysing the chemical reactions in which these substances are used and made.

Pupils learned that photosynthesis in producers makes glucose, a type of carbohydrate, which is used to make biomass and as a fuel for cellular respiration.

This unit covers the structure and function of sub-cellular components in eukaryotic and prokaryotic cells and explores DNA as the genetic material of organisms. It explains genetic terms, protein synthesis, and how genetic variants influence phenotypes.

Eukaryotic and prokaryotic cells

cover the outer surface of roots and absorb water and minerals 

transport water upwards from roots to leaves

control if the stomata are open or closed

transport glucose and amino acids up and down the plant

Match the specialised cell to their function. 

contain lots of mitochondria to transfer energy for active transport

contain a large permanent vacuole to store water

have broken down cell ends to create hollow tubes so water can flow easily

large surface area to increase absorption of water and mineral ions

Match the feature of the palisade cell to the advantage they provide. 

Xylem cell walls are thickened with {{}} ; this provides strength to the hollow tubes. 

have sieve plates which provide energy to move glucose

phloem are attached to companion cells that provide energy to move glucose

contain few sub-cellular structures so more glucose can can travel through

Which of these statements about phloem are correct?

they absorb water by osmosis to become turgid

What happens to guard cells at night time?

Which of these images is showing a plant cell?

Which part of the plant absorbs water and minerals?

Which of these processes do plants use to make glucose?

contains cellulose; provides strength to cell and support to plant

contains chlorophyll where photosynthesis takes place

contains cell sap which helps keep the cell turgid

Match each sub-cellular structure to their function.

Where does aerobic respiration take place in cells?

A cell that is adapted to perform a specific job is called a {{}} cell.
