Cells Learning Objectives 1 To revise basic cell structure 2 To revise cells tissues and organs 3 3 That chemical reactions in cells are controlled by enzymes using the example of the mitachondrion

Learning Outcomes • All can describe the structure and function of the organelle of animal cells • Most can describe the major organs and tissues of the body • Some can explain that enzymes control cell reactions using the example of the mitachondrion and respiration

How big is a cell? Most plant and animal cells are between 0. 025 µm and 60 µm in size – around half the diameter of a human hair – and too small to see without a microscope. The largest cell in the human body is the female egg cell, (ovum) at around 1, 000 µm in diameter. The smallest human cell is the sperm cell – the head is around 5 µm long.

What do cells contain?

What is aerobic respiration? Aerobic respiration is a series of reactions that release energy from glucose using oxygen. : glucose + oxygen carbon dioxide Aerobic Respiration takes place in mitochondria. Mitochondria are the energy-producing part of the cell. + water + energy

How do animal cells specialize? In animals, the first type of cells in the developing embryo are stem cells. These are unspecialized cells that go on to form all the different cell types in the adult. red blood cell nerve cell stem cell sperm cell muscle cell

How are animal cells adapted?

How do plant cells specialize? Unlike animals, many plant cells retain the ability to differentiate and specialize throughout their life. These cells are found in tissues called meristems. meristem cell root cell leaf cell sieve cell
