PLANT CELLS

Anatomy of a Plant Cell
Plant cells are eukaryotic cells , or cells with a membrane-bound nucleus. Unlike prokaryotic cells, the DNA in a plant cell is housed within the nucleus. In addition to having a nucleus, plant cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation. Organelles have a wide range of responsibilities that include everything from producing hormones and enzymes to providing energy for a plant cell. How are Animal and Plant Cells Similar and Different? Plant cells are similar to animal cells in that they are both eukaryotic cells and have similar organelles. Plant cells are generally larger than animal cells. While animal cells come in various sizes and tend to have irregular shapes, plant cells are more similar in size and are typically rectangular or cube shaped. A plant cell also contains structures not found in an animal cell. Some of these include a cell wall, a large vacuole, and plastids. Plastids, such as chloroplasts, assist in storing and harvesting needed substances for the plant. Animal cells also contain structures such as centrioles, lysosomes, and cilia and flagella that are not typically found in plant cells. Plant Cell Organelle Vocabulary: I.) *Cell wall* - a rigid supporting layer that surrounds the cells of plants and some other organisms. Only Plant Cells II.) *Chloroplast* - an organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food. Only plant cells. III.) Cell membrane - a thin flexible barrier that surrounds a cell and controls which substances pass in and out of the cell. Both Animal and plant cells IV.) Nucleus - in cells, a large oval organelle that contains the cell's genetic material in the form of DNA and controls many of the cell's activities. Both animal and plant cells V.) Ribosome - a small grain-shaped organelle in the cytoplasm of a cell that produces protein. both animal and plant cell. VI.) Cytoplasm - gell-like fluid that fills the region between the cell membrane and the nucleus. It moves constantly and supports organelles. Both animal and plant cells VII.) Mitochondria - rod-shaped organelles that convert energy in food molecules into energy the cell can use to carry out its functions. Both animal and plant cells VIII.) Endoplasmic Reticulum - an organelle that forms a maze of passage ways in which proteins and other materials are carried from one part of a cell to the other. Both animal and plant cells VX.) Golgi apparatus - an organelle in a call that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them and distributes them to other parts of the cell. both animal and plant cell. X.) Central Water Vacuole - a sac-like organelle that stores water, food and other materials. plant cells only . CONCEPTS REVIEW: I.) Watch the video: "Plant Cells". II.) Complete the activity aside. Make sure you use sketches, and label each organelle of the plant cell!
