This document discusses the parts of plant and animal cells. It defines a cell as the smallest unit of life and notes there are two main types - prokaryotic and eukaryotic cells. It then lists and describes the major organelles found in plant cells, such as the cell wall, chloroplast, cytoplasm, mitochondria, endoplasmic reticulum, nucleus, vacuole, lysosomes, Golgi complex and ribosomes. A similar list is then provided for the organelles commonly found in animal cells.
Cell-Basic Unit of Life
- 3. What is a cell? Parts of a plant cell Parts of a animal cell
- 4. What is a cell? -the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic Two types of cell Prokaryotic Eukaryotic
- 5. Parts of a plant cell Cell Wall Chloroplast Cytoplasm Mitochondrion Endoplasmic Reticulum Nucleus Vacuole Lysosome Golgi complex Ribosomes Plasma Membrane
- 6. Parts of a animal cell • Plasma Membrane • Mitochondrion • Nucleus • Endoplasmic Reticulum • Cytoplasm • Lysosome • Golgi complex • ribosomes
- 7. Cell Wall -a stiff covering that protects plant cells
- 8. Chloroplast -The cell organelle in which photosynthesis takes place. In this organelle the light energy of the sun is converted into chemical energy.
- 9. Cytoplasm -refers to the jelly-like material with organelles in it.
- 10. Mitochondrion -are membrane-enclosed organelles distributed through the cytosol of most eukaryotic cells. Their main function is the conversion of the potential energy of food molecules into ATP
- 11. Endoplasmic Reticulum • It is a network of membranes throughout the cytoplasm of the cell. There are two types of ER. When ribosomes are attached it is called rough ER and smooth ER when there are no ribosomes attached.
- 12. Nucleus • The nucleus is the control center of the cell. It is the largest organelle in the cell and it contains the DNA of the cell. The DNA of all cells is made up of chromosomes.
- 13. Vacuole - Vacuoles are storage organelles in cells. Either structure may store water, waste products, food, and other cellular materials. In plant cells, the vacuole may take up most of the cell's volume.
- 14. Lysosomes Lysosomes function as the cell's recycling compartment.
- 15. Golgi complex -It is organelle in the cell that is responsible for sorting and correctly shipping the proteins produced in the ER
- 16. Plasma Membrane Contains cell contents
- 17. Ribosomes • Organelles that help in the synthesis of proteins. Ribosomes are made up of two parts, called subunits.
