Answer:

WHITE BLOOD CELL (WBC)

White blood cell. ... White blood cells (WBCs), also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.

VACUOLE

A vacuole is a membrane-bound organelle which is present in all plant and fungal cells and some protist, animal and bacterial cells

UNICELLULAR

A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. ... In contrast, even the simplest multicellular organisms have cells that depend on each other to survive

TISSUE

Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial

PSEUDOPODIA

A pseudopod or pseudopodium (plural: pseudopods or pseudopodia) is a temporary arm-like projection of a eukaryotic cell membrane that are developed in the direction of movement. Filled with cytoplasm, pseudopodia primarily consist of actin filaments and may also contain microtubules and intermediate filaments.

PROKARYOTES

Prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes.

PLASTID

The plastid is a membrane-bound organelle found in the cells of plants, algae, and some other eukaryotic organisms. They are considered endosymbiotic Cyanobacteria, related to the Gloeomargarita. Plastids were discovered and named by Ernst Haeckel, but A. F. W. Schimper was the first to provide a clear definition.

PLASMA MEMBRANE

The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell's contents and the outside of the cell. It is also simply called the cell membrane. ... It is semi-permeable and regulates the materials that enter and exit the cell

ORGANELLES

organelle. : a specialized cellular part (such as a mitochondrion, chloroplast, or nucleus) that has a specific function and is considered analogous to an organ.

ORGAN

a part of an organism which is typically self-contained and has a specific vital function.

NUCLEUS

The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.

NUCLEOLUS

The nucleolus is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis. Nucleoli also participate in the formation of signal recognition particles and play a role in the cell's response to stress.

NUCLEAR MIEMBRANE

nuclear membrane. : a double membrane enclosing a cell nucleus and having its outer part continuous with the endoplasmic reticulum. — called also nuclear envelope. — see cell illustration.

MULTICELLULAR

Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. ... Multicellular organisms arise in various ways, for example by cell division or by aggregation of many single cells.

GENE

gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function.

EUKARYOTES

An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. The cells of eukaryotes also contain an endoplasmic reticulum and numerous specialized organelles not present in prokaryotes, especially mitochondria, Golgi bodies, and lysosomes.

CYTOPLASM

The jellylike material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus. The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and (in green plants) chloroplasts, are contained in the cytoplasm.

CHROMOSOME

The chromosomes of a cell are in the cell nucleus. They carry the genetic information. Chromosomes are made up of DNA and protein combined as chromatin. Each chromosome contains many genes. Chromosomes come in pairs: one set from the mother; the other set from the father.

CHLOROPLAST

Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells..

Answer:

the outermost membrane is cell membrane, smallest unit of life and the structural and functional unit of life is cell, A green type of pigment present in plant cell called chloroplast, chromosomes 46 present in human body ,the fluid present in cell is called cytoplasm, well defined cells are eukaryotic, it carry parents characteristics to the offspring, those organisms which carry more than one cell called multicellular, the membrane present around the nucleolus, it cantrol all the metamaorbic activites , group of tissues is called organ , the small things present in cell are organelles, it is known as selectively permeable membrane it allows enter and exist selective material inside the cell
