What are the biological themes?

The five central themes of biology are structure and function of cells, interactions between organisms, homeostasis, reproduction and genetics, and evolution.

What is the study of cells and organelles?

Cell biology is the study of cell structure and function, and it revolves around the concept that the cell is the fundamental unit of life.

What is the cell membrane and why is it important to your cells?

The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

What characteristics of the cell membrane determine what gets into the cell and what does it?

Cell membranes only allow some molecules through. This characteristic is why cell membranes are selectively permeable. They are not impermeable (not letting anything pass) nor are they freely permeable (letting everything can pass). This quality allows a cell to control what enters and exits it.

What do genetics study?

Genetics is the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.

What is the importance of studying cell?

Studying cells helps us understand how organisms function. Cellular components work together to carry out life functions. Cellular processes enable organisms to meet their basic needs.

What is a nuclear membrane function?

A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
