The three main parts of a cell, following their functions.
Introduction:
The cells are considered as the basic functional and structural unit of an organism’s body. A cell is typically called as the building block of life, which aggregates to form tissue, organ, and organ system.

Explanation of Solution
The three different parts of the cell are mentioned below:
1. Plasma membrane: The outer surface that separates the internal and the external environment of a cell is called as plasma membrane or cell membrane. It is composed of a lipid bilayer, which is selectively permeable. It works as the barrier, in order to control influx and efflux of the molecules or ions across the cell.
2. Nucleus: It is the most important part of the cell. It consists of the hereditary information of the cell in the form of DNA. Furthermore, it controls all the activities of the cell, like growth, intermediary
3. Cytoplasm: The cytoplasm is the fluid present between the nucleus and the cell membrane. It comprises various organelles like ribosomes, mitochondria, centrioles, endoplasmic reticulum, lysosomes, and so on. It is the center for most of the cellular activities like protein synthesis, photosynthesis (in plants), and
Thus, the three main parts of the cell are nucleus, plasma membrane, and cytoplasm. Plasma membrane acts as the barrier between the cellular external and internal environment and allow selected molecules to cross through it. Nucleus control all the cellular activities as it contain the hereditary material i.e. DNA. Cytoplasm consist several organelles and acts as the center for most of the cellular activities.

Color the line that represents all ancestors of the Eastern white pine tree green (but only the ancestral line NOT shared with other organisms) 2. Oncle the last common ancestor of the Colorado blue spruce tree and Eastern white pine tree. 3. Put a box around the last common ancestor of the sugar maple tree and the dogwood tree. 4. Put a triangle around the last common ancestor of the red pine tree and the american holly bush. 5. Color the line that represents all ancestors of the Ponderosa pine tree red (including all shared ancestors). 6. Color the line that represents all ancestors of the American elm tree blue (including all shared ancestors). 7 Color the line that represents all ancestors of the Sabal palm tree purple (including all shared ancestors) 8. Using a yellow highlighter or colored pencil, circle the clade that includes all pine trees. 9. Using a orange highlighter or colored pencil, circle the clade that includes all gymnosperms 10. Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward

Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?arrow_forwardThe patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours.
