Biology Flashcards
Cell theory?
- All living things are composed of cells
- Cells are the basic structure for all living things
- New cells are produced by existing cells
Fragmentation?
When a part of an animal breaks off and grows into a new organism
Vegetative Reproduction?
When a part of a plant breaks off and grows into a new organism
Spore formation?
Cell division. Genetically identical
Binary Fusion?
“Rapid Growth” parent undergoes cell division. Genetically identical
Budding?
Offspring grow off of parent until full size, then break off. Identical
Mitosis?
The process that divides the nuclear material during cell division. Asexual
Nucleus?
“Information centre” for reproduction and other functions. Where DNA is stored.
Centrioles?
Creates spindle fibres in cell division
Ribosomes?
Sites of protein
Nuclear Membrane?
Controls material transport in and out of nucleus. RNA is stored here
Two types of RNA?
Messenger and transfer
Endoplasmic Reticulum?
Smooth is fats and hormones
Rough is proteins
Cell wall?
Only in plants, protects them
Cell membrane?
Controls material transport
Mitochondria?
“Powerhouse” of the cell. Mom DNA
Lysosomes?
Centres of cellular digestion “recycling”
Vacuole?
“Reservoirs”
Chloroplasts?
Energy in plants cells. Sites for food manufacture.
Centrosome?
Contains centrioles that are functional during reproduction. In animal cells
Chromosomes are made of?
DNA and protein
Chromosomes?
DNA. Agents for distribution
Cytoplasm?
Provides an organized watery environment. Contains organelles
Golgi apparatus?
Synthsmesizes carbohydrates and packages secretions for discharge from the cell.
