• The two types of Biomes is terrestrial and aquatic biomes
• Terrestrial Biomes are the group based on the type of the plants they support
• Aquatic Biomes are the group based on the type of animals that live there.
• The cell theory states that cells are the basic units of all living things
• nucleus is located near the center of a cell. It is the control center of the cell and it contains the genetic material
• The cell theory states that all living organisms are composed of cells
• The cell membrane, which is a thin coat of lipids that encloses the cell
• The cell membrane serves as the boundary between the inside of the cell and the outside environment
• The cell theory states that new cells are produced from pre-existing cells
• The nucleus, which is a jelly-like material that encloses and protects the organelles
• The organelles, or "little organs", which are tiny celluar structures that serve specific functions within a cell
• Common organelles found in cells are the mitochondria, ribosome, endoplasmic reticulum, golgi bodies etc
• The nucleus that is surrounded by a double-layered membrane called the nuclear membrane or nuclear envelope
• Reproduction refers to the process by which new organisms are produced from a parent organism
• Diploid is a type of cell that contains the total genetic materials present in the species
• Haploid is a type of cell that contains half of the total genetic materials present in the species
• Pistil is the female component of a plant
• Ovary , stigma, and style is a part of the carpel
• Asexual is a type of a reproduction produces individuals that are highly identical to the parent plant
• Gametes are sex cells or reproductive cells
• Rhizomes refers to horizontal stem that develops from the vertical stem of a grown plant
• Rhizomes occurs when an underground stem forms a bulb
• apomixis refers to a process where in a plant can produce seed without fertilization
• Ecosystem consists of a community of organisms living together and interacting with the non living components
• Biotic factors refer to all living things within an ecosystem
• Abiotic factor refers to physical environmental conditions such as temperature, light, water, air pressure, soil composition, etc.
• pH refers to the level of acidity and alkalinity
• Producers refers to organisms that are capable of producing own food
• Decomposer refers to organisms that decompose dead parts of living organism
• Detritivorce refers to organisms responsible for decaying of matter and reabsorption of nutrients back to the soil
• Aquatic biomes comprises 70% of the earth's surface
• Marine biome has very high salinity
• Desert biome is considered to be the driest
• Tropical rainforest biome receives the highest amount of rainfall
• tropical rainforest biome receives 10 to 30 inches of rainfall each year
• Tundra is considered to be the coldest and harshest of all biomes
• Erythrocytes delivers oxygen gas to the different parts of the body througn blood flow
• commensalism does not involve harming another organism
• parasitism refers to a relationship where one organism benefits at the expense of other
• mutualism refers to a relationship where both organisms benefit
