FAQs

What is the structure of the cell answer? ›

It includes features from all cell types. A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

Mnemonics: Create a memorable acronym or mnemonic for each organelle and its function. For example, "MVP" for mitochondria (energy production), "GCP" for Golgi apparatus (protein processing), and "CNC" for chloroplasts (photosynthesis).

Answer and Explanation:

Some of the structures inside a cell that help it live to perform its role in an organism are chloroplasts, mitochondria, ribosomes, and the nucleus. Plant and algae cells contain chloroplasts, in which the chemical reaction of photosynthesis takes place.

What structures are present in an animal cell, but not in a plant cell? centrioles and lysosomes are present in animal cells but not in plant cells.

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

The light microscope remains a basic tool of cell biologists, with technical improvements allowing the visualization of ever-increasing details of cell structure. Contemporary light microscopes are able to magnify objects up to about a thousand times.

The phrase I use to remember is PMAT, with the stages of mitosis as Prophase (supercoiling), Metaphase (alignment), Anaphase (poles) and Telophase (division). Being able to remember just these few words will allow you to describe in detail what happens in each stage.

In this unit on cell theory and cell structure and functions, 7th grade students will be able to recognize the different levels of organization in plants and animals including cells, tissues, organs, organ systems, and organisms (7.12C).

Eukaryotes (meaning 'true nuclei" where "karyote" is derived from the ancient Greek for "kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Mitochondria – organelles that, using oxygen, convert nutrients into energy that can be used by the cell.

What are structures in cells that perform life functions called? ›

The structures of the cell, carrying out life functions are called organelles.

Final answer : The two structures found in plant cells that are absent in animal cells are cell wall and chloroplast.

​Nuclear Membrane

The nuclear membrane is a double layer that encloses the cell's nucleus, where the chromosomes reside. The nuclear membrane serves to separate the chromosomes from the cell's cytoplasm and other contents.

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours.

Structure of the T-cell receptor

T-cell receptors consist of two polypeptide chains. The most common type of receptor is called alpha-beta because it is composed of two different chains, one called alpha and the other beta.

Non-lymphoid structural cells of tissues are recipients of inflammatory signals from immune cells, but they also make inflammatory products that can affect the migration, localization, and activity of immune cells in the tissues.

A simple cell consists of two solid electrodes placed in an electrolyte connected together by an electrical conductor such as wire. The two electrodes must be two different metals. The electrolyte can be acid solution, alkaline solution, salt solution or even a fruit such as orange or lemon.
