Unit 1- Cell Biology

• The nucleus contains DNA which stores genetic instructions for controlling cell activities.
• Blood carries oxygen, nutrients, hormones and waste products around the body.
• Plant and animal cells have similar components including a nucleus, mitochondria, ribosomes, rough endoplasmic reticulum, Golgi apparatus, lysosomes, and cytoplasm.
• The cell is the fundamental structural and functional unit of life.
• The main function of the circulatory system is to transport substances around the body
• Arteries carry blood away from the heart under high pressure
• Proteins control the structure and function of cells
• Ribosomes make proteins using information from mRNA
• Cell membranes are made up of phospholipids with embedded proteins that control what enters or leaves the cell
• Chloroplasts contain chlorophyll which is used to capture light energy during photosynthesis
• Cells are made up of prokaryotic or eukaryotic organisms.
• Mitochondria produce most of the energy needed by cells through aerobic respiration
• Prokaryotes lack membrane-bound organelles while eukaryotes contain them.
• Animal cells also contain centrosome/centrioles, cytoskeleton (microtubules), smooth ER, vacuole, chloroplasts, and plasma membrane.
