What is the correct order of the cells?
Cell → Tissue→Organ→Organ system→Organism.
What is the correct order of organization within the body smallest to largest?
The levels, from smallest to largest, are: molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere.
What is an example of a cell?
A cell is defined as the smallest unit of an organism with a nucleus. An example of a cell is a unit in the tissue of an animal muscle. A small enclosed cavity or space, such as a compartment in a honeycomb or within a plant ovary or an area bordered by veins in an insect’s wing.
What are 2 examples of cell?
There are many different types of cells. For example, in you there are blood cells and skin cells and bone cells and even bacteria. Here we have drawings of bacteria and animal cells.
What are the 2 types of cell?
Cell types. Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.
What is tissue example?
There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is tissue explain?
In biology, tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
What is tissue answer?
Question 1: Define the term “tissue”. Answer: A group of cells which is meant to perform a specific function is called tissue. Answer: Simple tissues are composed of similar cells, while complex tissues are composed of different types of cells.
What is tissue class 8?
A group of cells having similar structure and performing similar function are known as tissues. A group of tissues forms an organ which performs a single function. It consists of small pores through which important substance comes in and out of the cells.
What is tissue class 9?
A tissue is defined as a cluster of cells which are similar in structure and work together to perform a particular function. 2. The use of tissues in multicellular organisms is to provide structural and mechanical strength as well as to allow division of labour.
What is tissue and types?
Tissues are groups of cells that have a similar structure and act together to perform a specific function. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial.
What are Pseudopodia Class 8?
A temporary arm like projections of eukaryotic cell membrane is called pseudopodia. It is temporarily filled in the cytoplasm organelle of the cell. Pseudopods extend and contract by the reversible assembly of actin subunits into many microfilaments.
What are Pseudopodia answer?
Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example. Pseudopods can also capture prey by phagocytosis.
How is Pseudopod created?
Pseudopodia are formed by some cells of higher animals (e.g., white blood corpuscles) and by amoebas. During amoeboid feeding, pseudopodia either flow around and engulf prey or trap it in a fine, sticky mesh. Protozoans have four types of pseudopodia.
What is protoplasm Class 8?
Protoplasm is the complex, semifluid, translucent substance that constitutes the living matter of plant and animal cells. Protoplasm comprises of proteins, fats, and other molecules suspended in water. It includes both the contents of nucleoplasm and cytoplasm.
What are the main parts of protoplasm?
Protoplasm is defined as the organic and inorganic substances that constitute the living the nucleus, cytoplasm, plastids and mitochondria of the cell.
What is called protoplasm?
Protoplasm, the cytoplasm and nucleus of a cell. The term was first defined in 1835 as the ground substance of living material and, hence, responsible for all living processes. Advocates of the protoplasm concept implied that cells were either fragments or containers of protoplasm.
Where is protoplasm present?
It occurs everywhere in the cell. In eukaryotes, the portion of protoplasm surrounding the cell nucleus is known as the cytoplasm and the portion inside the nucleus as the nucleoplasm.
What are the two types of protoplasm?
Protoplasm exists in two forms: a liquid-like sol state or a jelly-like gel state.
Is it true that nucleus is the brain of the cell?
The nucleus is considered the brain of the cell. The nucleus of every cell contains DNA, the hereditary information for an organism. The nucleus also controls the cell’s individual functions such as cell growth, protein synthesis, cell division, and reproduction.
