Water is an essential molecule for life. Complete the statements. Water moves into and out of cells by ........................ Water is known as a ................... because it can dissolves a solute, resulting in a solution

Osmosis and Solvent

10

A plant was not watered for one week. Look at a series of photographs of the plant during the week. Explain how the lack of water has affected the support of the leaves of the plant shown in the photographs. Use the term turgor pressure

lack of turgor pressure, (mesophyll) cells not providing support / cell collapses, (lack of water means cells become) plasmolyse ;

10

Some substances move into cells by the process of diffusion. State the name of the outer part of an animal cell that substances move through during diffusion.

Cell membrane

10

The diagram shows a palisade mesophyll cell and the same palisade mesophyll cell after it has been placed in a concentrated sugar solution for twenty minutes. Explain why the cell in the second diagram changed

water moves out of the cell, osmosis, sugar solution more concentrated than cell contents

10

State the name of the process by which water molecules move into plant roots

osmosis

10

Describe the ways in which diffusion is different to active transport

look the table

10

Give 2 examples in diffusion in our daily life

spraying a perfume, making a tea, dissolve the sugar in the water

10

Give 2 examples of osmosis

The absorption of water from the soil, Potato In Sugar Solution

10

Mention 2 examples of active transport

uptake of glucose by epithelial cells in the villi of the small intestine, uptake of ions from soil water by root hair cells in plants

10

Gas exchange occurs at the alveoli. Describe how oxygen molecules move from the alveoli into the blood.

diffusion, across (cell / permeable) membranes, high concentration to low concentration (of O2 )

10

Mention 3 factors that influence diffusion

Surface area to volume ratio, Concentration Gradient, temperature

10

What is turgid condition?

When water moves into a plant cell, the vacuole gets bigger, pushing the cell membrane against the cell wall.

10

What is plasmolyzed condition?

he process of contraction or shrinkage of the protoplasm of a plant cell and is caused due to the loss of water in the cell
