what are the similarities and differences in cells from various living organisms?
308645
Cells of plants, animals, fungi, protists, and bacteria have similarities and differences. All of these have nuclei and mitochondria, but plants and some protists have chloroplasts. Animal cells lack cell walls. All eukaryotic cells share common characteristics but also have differences in their cell structures.

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.

All living things are made of cells, use energy, respond to stimuli, grow and reproduce, and maintain homeostasis. All living things consist of one or more cells. Cells are the basic units of structure and function of living organisms.

The second main difference is in the structure of the cell itself. Animal cells are smaller than plant cells and have a membrane around them that is flexible and allows molecules, gases and nutrients to pass into the cell. Plant cells are larger and in addition to a membrane they have a rigid cell wall.

How do plant and animal cells differ? Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs.

Animal cells and plant cells are similar in that they are both eukaryotic cells. These cells have a true nucleus, which houses DNA and is separated from other cellular structures by a nuclear membrane. Both of these cell types have similar processes for reproduction, which include mitosis and meiosis.

The main difference between animal cell and human cell is that the animal cell may have different sizes of genomes depending on the species whereas the human cell has 3 billion base pairs in its genome. ... Both do not have a cell wall , large vacuole, as well as chloroplasts.

Plant Cells. Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes.

All living things are composed of cells. Unicellular organisms are composed of a single cell, while multicellular living things (such as plants, animals, and human beings) are composed of a large number of cells. A car is not composed of cells. ... A car stays the same in size and shape over its life time.

The cell is the fundamental unit of structure and function in living things. All organisms are made up of one or more cells. Cells arise from other cells through cellular division.

Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. ... Plant cells can be larger than animal cells.

Cell composition and function vary considerably both between organisms and, in the case of complex multicellular organisms, between different tissues and organs within the same organism. But all cells have a number of elements in common.

As nouns the difference between organism and cell is that organism is (biology) a discrete and complete living thing, such as animal, plant, fungus or microorganism while cell is a single-room dwelling for a hermit or cell can be (us|informal) a cellular phone.

Lesson Summary. All living things are made of cells, use energy, respond to stimuli, grow and reproduce, and maintain homeostasis. All living things consist of one or more cells. Cells are the basic units of structure and function of living organisms.
