---|---|---|---|---|---|
show | The variety of different species living in a habitat.
🗑
|
||||
What is the difference between an ecosystem and a habitat? | show 🗑
|
||||
show | A population is all the organisms of the same kind living in the same place, a community is all the populations living in one place.
🗑
|
||||
show | Natural ecosystems like native woodlands and lakes.
🗑
|
||||
What is the word equation for photosynthesis? | show 🗑
|
||||
How is glucose stored in plants? | show 🗑
|
||||
When do plants carry out respiration? | show 🗑
|
||||
Give four ways plants use glucose. | show 🗑
|
||||
Name the limiting factors of photosynthesis | show 🗑
|
||||
show | It is insoluble in water and does not affect the concentration of a cell. It will not affect osmosis.
🗑
|
||||
show | Broad, thin, waterproof transparent epidermis top layer, stomata to allow CO2 to enter, a palisade layer with lots of chloroplasts to absorb light.
🗑
|
||||
Give a definition of diffusion | show 🗑
|
||||
show | When there is a shorter distance, a greater concentration gradient and a greater surface area.
🗑
|
||||
Give a definition of osmosis | show 🗑
|
||||
How does osmosis affect a plant cell? | show 🗑
|
||||
show | It would absorb water and burst as RBCs do not have a cell wall.
🗑
|
||||
show | Carbon dioxide, the oxygen in water is released by the plant as a product of photosynthesis.
🗑
|
||||
Four factors that increase the rate of transpiration. | show 🗑
|
||||
show | For cooling a plant, photosynthesis, support and movement of minerals.
🗑
|
||||
show | The evaporation and diffusion of water out of leaves.
🗑
|
||||
How is a leaf adapted to reduce water loss? | show 🗑
|
||||
Four minerals in fertilisers. | show 🗑
|
||||
show | To make proteins for growth and repair.
🗑
|
||||
How do plants take in minerals at their root hair cells. | show 🗑
|
||||
show | They are long and have a large surface area for absorption.
🗑
|
||||
List four factors that are important in decay. | show 🗑
|
||||
show | Canning, cooling, freezing, drying, adding salt or sugar and adding vinegar.
🗑
|
||||
show | chemical reactions within cells that require energy released by respiration
🗑
|
||||
show | it is where a molecule has to be the correct shape to be able to fit into the active shape of an enzyme
🗑
|
||||
show | it will denature
🗑
|
||||
show | they speed up chemical reaction
🗑
|
||||
show | they make them according to the instuctions carried in genes
🗑
|
||||
show | if it only a little higher it can speed up the reaciotn
🗑
|
||||
enzymes need an optimum | show 🗑
|
||||
show | light energy absorbed by the chemical chlorophyll,energy used to bring about the reaction between carbon dioxide (co2) and water (h2o) to produce glucose (c6h12o6), oxygen (o2) produced as a waster product
🗑
|
||||
show | starch for storage
🗑
|
||||
show | from plant roots to make some chemicals needed by the cells
🗑
|
||||
show | diffusion
🗑
|
||||
show | A transect is line across a habitat or part of a habitat. It can be as simple as a string or rope placed in a line on the ground. The number of organisms of each species can be observed and recorded at regular intervals along the transect
🗑

|
||||
show | c6h1206+6o2=6co2+6h2o
glucose+oxygen=carbon dioxide+water
🗑
|
||||
anaerobic respiration in animals | show 🗑

|
||||
show | it contains an enzyme for aerobic respiration
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
