PPT-Plant Cell Structure and Cell Processes

Unit Objectives 1 Explain the structures of plant cells and important cell processes a Describe the structures of a typical plant cell and their functions b Compare and contrast mitosis and meiosis. OCR AS Biology. Unit 1: Cells, Exchange and Transport. Learning objectives. To understand and discuss the basis of cell theory based upon milestones in cell biology. To carry out practical work on cell size and magnifications using a light microscope. a hierarchy of life from cells to ecosystems.. HIERARCHY OF LIFE. HIERARCHY OF LIFE. Cell: smallest functional unit of life. Ex. Heart cell (cardiac muscle cell). Tissue: made of similar cells that have the same function. Surface markers. Structure: Variable, integral proteins or glycolipids in plasma membrane. Function: Identify the cell. Example: MHC complexes, blood groups, antibodies. Septate junctions/tight junctions. Cell membrane is like the doors on a car. They regulate what goes in/out.. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.. The endoplasmic reticulum is like the fuel lines on a car. It lets a passage way for fuel to flow like proteins do in the endoplasmic reticulum . Recall your work yesterday. When classifying cells, what are the two groups scientists separate cells into? . USING A MICROSCOPE. Light Microscopes and Total Power Magnification. Uses. We can use microscopes to observe cells in greater detail. Lesson . 2. Plant Responses. plant hormones produced by root tips that increase the rate of cell . division. cytokinins. plant hormones produced by root tips that increase the rate of cell . division. Cell membrane is like the doors on a car. They regulate what goes in/out.. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.. The endoplasmic reticulum is like the fuel lines on a car. It lets a passage way for fuel to flow like proteins do in the endoplasmic reticulum . Structures, Functions and Organelle Relationships. p.50-50 in textbook. Animal Cell. Plant Cell. Cell Membrane & Cell wall. The cell membrane (plasma membrane) creates a cell boundary and helps to regulate the transport of molecules in and out of the cell (in plant & animal cells). Structure. Main component is phospholipids that are arranged in a double layer (. bilayer. ). Has scattered proteins within the phospholipids. Regulate what enters/leaves cell. Function . Nucleus. Structure. Cell Membrane. Cell Wall. Cytoplasm. Chloroplasts. Mitochondria. Nucleus. Vacuole. DRAW this table…. DRAW this table…. Plant Cell. Animal Cell. cytoplasm. chloroplast. vacuole. Cell. membrane. nucleus. Extended Learning — Activities and Projects1.Visit a laboratory for senior secondary students in your school orin a neighbouring school. Learn about the functioning of aunder the microscope.2.Tal The ultrastructure of eukaryotic cells. Spec. Animal Cell Plant Cell. Starter. In pairs - Identify the main similarities and differences between animal and plant cells. Animals vs. Plants. Much larger than prokaryotic cells having two enveloped systems. True cells occurring in plants and animals . Though they have different shape size and physiology but all cells are typically composed of plasma membrane cytoplasm and its organelles i.e. mitochondria, endoplasmic reticulum . PLANT PHYSIOLOGY. *. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants.. . * Plant physiology closely related fields include Plant Morphology, Plant Ecology, Phytochemistry , Cell Biology, Genetics, Biophysics and Molecular Biology..
