6. Cross-section of an animal cell golgi body* rough endoplasmic reticulum* vacuole cell membrane ribosome* cytoplasm nucleus *can only be seen under an electron microscope nucleolus smooth endoplasmic reticulum* mitochondrion*
7. Parts of an animal cell Please refer to TB Pg 17 – 23 for more information. fluid-filled space enclosed by a membrane; contains water and food substances ; present as many small vacuoles Vacuole contains genetic information (chromatin) , or instructions for making molecules (DNA) and controls all cell activities. nucleus breaks down glucose to release energy (during cellular respiration). Mitochondrion (singular) Mitochondria (pl.) composed mostly of water, where most chemical reactions take place cytoplasm surrounds the cell as a partially permeable membrane; controls the entry and exit of substances cell surface membrane Functions Name

16. Plant Cell vs Animal Cell Cell wall is present. Cell wall is absent. Chloroplasts are present. Chloroplast are absent. Centrioles are absent. Centrioles are present. A large central vacuole Many small vacuoles Animal Cell Plant Cell
28. Organization of Cells cells tissues organs systems A group of similar or different cells work together for a specific function. E.g cardiac muscle Different tissues work together for a specific function. E.g Heart Different organs work together to support the whole system. E.g. circulatory system The basic unit of living things. E.g. muscle cell organism Different systems work together to support the whole organism. E.g. Human
29. Are all organisms made of many cells? amoeba – unicellular organism plants and animals – multicellular organisms
Editor's Notes
Need to take note to the students that this picture is only possible in electron microscope. Circle the diagram
All these organelles have been taught in sec 1, so we Test the students for the equation for cellular respiration glucose + oxygen -> water + carbon dioxide + energy
Test the students for the equation for cellular respiration glucose + oxygen -> water + carbon dioxide + energy Golgi bodies also known as golgi apparatus
A clearer picture of how the cell look like under electron microscope, show the different between membrane bound ribosomes and free ribosome
Test the students for the equation for cellular respiration glucose + oxygen -> water + carbon dioxide + energy Golgi bodies also known as golgi apparatus
Allow students to work in pair to come up with the differences between plant cell and animal cell
