DAY – 1 RECAP ACTIVITY LESSON – CELLS Identify the following ◦Name the part of an animal cell called as control centre____________. ◦This part of an animal cell can be passed down from one generation to another________________. chloroplast nucleus chromosomes cytoplasm cell sap Identify the following ◦A jelly like material fills the cell ____________. ◦It controls the movement of materials in and out of the cell _______________. cell membrane chloroplast cytoplasm nucleus Label the part of an animal cell and mention the function performed by it. Animal cell keys ◦ Nucleus ◦ DNA / chromosomes ◦ Cytoplasm ◦ Cell membrane Label the organelles and explain the functions Label the organelles and explain the functions – Keys 1. Name the scientist credited with coining the word cell. 2. Why cell is an important part of an organism? 3. What is unicellular organism? 4. What is multicellular organism? 5. How unicellular is different from multicellular? Give one example for each. keys 1. Robert Hooke. 2. Cell is the basic structure for a living organism it if fully alive and performs all the important functions to keep an organism alive. 3. Single celled organism (or) the organism which has only one cell which performs all the body functions 4. Organism with many cells or more than one cell are called multicellular all the cells perform certain functions together to keep the organism alive. 5. Unicellular has one cell and multicellular has many cells that performs the body functions. E.g. paramecium, euglena and humans, fish ANIMAL CELL PLANT CELL • No chloroplasts. • Has chloroplasts. • No Cellulose cell wall. • Has cellulose cell wall. • Contains vacuoles which are small and numerous. • Contains one to a few large vacuoles. • The cytoplasm fills the cell. • The cytoplasm is reduced to a thin lining. • No starch grains in the cytoplasm. • Starch grains are commonly found in the cytoplasm.
