Plant Cell

1. Characteristics and structure of secondary cell wall

1.1. consists of pits

1.2. consists of cellulose fibres impregnated with carbohydrates and permeated with lignin . The fibres are arranged neatly.

1.3. offers protection to the cell

1.4. The cell wall lends support and gives shape to the plant cell

1.5. Permeable

1.6. Cell wall

2. Diagram and functions of chloroplast

2.1. chloroplast use photosynthesis to make ATP which is energy for the cell.

2.2. Takes in carbon dioxide and water

2.3. Contain chlorophyll

2.4. Gives off oxygen

2.5. Produces glucose

2.6. Chloroplast

3. Names of other cell organelles

3.1. Cell membrane

3.2. lysosome

3.3. ribosome

3.4. Golgi apparatus

3.5. Mitochondria

3.6. endoplasmic reticulum

3.7. cytoplasm

4. Differences from animal cells

4.1. Plant cell

4.2. contain plastids

4.3. have cell walls

4.4. No centrioles

4.5. Only one, large vacule

4.6. Animal cell

5. Functions of cell nucleus

5.1. To control the cells metabolism

5.2. Differentiation and specialization of cells

5.3. The transfer of hereditary information

5.4. reproduction of cells/organisms

5.5. Nucleus

6. Functions of vacuole

6.1. Storage of dissolved substances like sugar and salt

6.2. To lend support the the cell by means of turgor pressure

6.3. To promote osmosis by creating a low water potential inside the plant cell

6.4. Vacuole

7. Characteristics and structure of primary cell wall

7.1. The cell wall lends support and gives shape to the plant cell

7.2. offers protection to the cell

7.3. consists of cellulose fibres impregnated with carbohydrates and permeated with pectin . The fibres are arranged in a disorderly manner.

7.4. consists of pits

7.5. Permeable

7.6. Cell wall

8. Names and functions of other plastids

8.1. Chromoplasts

8.1.1. Chromoplast imparts color and found in some cells of more complex plants.

8.1.2. Chromoplasts are coloured plastids other than green and found in coloured parts of plants such as petals of the flower, pericarp of the fruits etc.

8.1.3. The primary functions of chromoplasts are synthesis and accumulation of carotenoid pigments.

8.2. Leucoplasts

8.2.1. Leucoplast is the non-pigmented plastid organelles, found in plant cells.Leucoplasts are colourless plastids that are stored in starch and protein granules.

8.2.2. The function of Leucoplasts is transforming glucose in to starch and storing it and also storing of oil.
