Earth and Life Science Flashcards
It involves a single parent that produces a genetically identical offspring
Asexual reproduction
It involves two parents of the opposite sex a male plant or animal that contributes genetic material through sperm( animals and humans ) or pollen ( plant )to a female plant or animals
Sexual Reproduction/Fertilization
The process by which cells obtain food molecules to support their other activities
Nutrition
The process by which food particles are broken down into smaller soluble units suitable for all use with the help of enzymes
Digestion
The process by which cells absorb water minerals and other essentials to life from their environment
Absorption
The process by which all cells organize complex chemicals from simple building units or substances
Biogenesis
Products of all cell activity which are not needed for further cell functioning are eliminated
Excretion
Insoluble non digested particles are eliminated by the cell
Egestion
Substances that are synthesized by the cells are expelled from the membrane this elimination process helps in the functioning of the body
Secretion
Includes the locomotion of cell by means of special structures like cilia or flagella
Movement
Cell respond or rich to external factors or conditions around themselves can alter their functions in response to change their environment
Irritability
Breaking down food molecules into chemical energy needed by all cells in order to functions
Respiratory
A cell copies or replicates its dna and increases its number by the cell division it gives rise to new cells as a result organisms grow
Reproduction
Is the bodies ability to maintain a stable interval environment despite external changes it is crucial for the proper functioning and survival of living organisms
Homeostasis
Is a crucial process in the human body to eliminate harmful by products and maintain overall health
Waste Removal
They surround the plants reproductive parts of the flower and they are usually a colorful structure arranged in a circle around the top of the stem
Petals
Modified leaves that in case a developing flower they are the sterile parts of the flower and are usually green or leaf like
Sepals
In this type of reproduction the parent cell divides into two equal parts each containing a nucleus these are called daughter cells the daughter cells are genetically and physically similar to the parent cell this type of asexual reproduction can be seen in organism such as amoeba bacteria etc
Binary Fission
This type of asexual reproduction is exhibited by planaria a species of flatworm here the parent body breaks into several places where each place grows into a new individual the detachment of the body parts is intentional
Fragmentation
Is a method of asexual reproduction where a new organism develops from an outgrowth from the parent body known as a bud this derived nutrition from the parent for growth and development once grown the new organism detach from the parent body this process is called _____ this type of reproduction can be seen in hydra
Budding
The male reproductive organ of a flower it consists of an anther and filament filament is a slender part of stamen that supports the answer the answer is responsible for producing pollen that contains sperm cells
Stamen
The female reproductive organ of a flower it consists of an ovary stigma and style the stigma has an adhesive area that allows the pollen from the stomach to stick to the ____ the style is a stock structure between the ovary and the stigma the ovary is responsible for producing the egg cells
Pistil
An ecosystem is a community of organism and their______environment
Physical
A female reproductive organ that produces egg
Ovary
Pistil:stigma ; Anther:_____
Stamen
Organisms are more likely to reproduce and pass on their______information to their offspring
Genetic
