Any membrane-bound structure inside a cell is known as an organelle. Organelles perform specific functions essential for the cell's life and activities, such as energy production, protein synthesis, and waste management. Examples of organelles include the nucleus, mitochondria, and endoplasmic reticulum. These structures are crucial for maintaining the overall health and functionality of the cell.
What else can I help you with?
What is the cell that lacks true nucleus and organelles?
The cell that lacks a true nucleus and organelles is known as a prokaryotic cell. Prokaryotes, which include bacteria and archaea, have a simpler structure compared to eukaryotic cells. Their genetic material is not enclosed within a membrane-bound nucleus, and they typically lack membrane-bound organelles. Instead, their cellular processes occur within the cytoplasm or are associated with the cell membrane.
What is a fluid filled membrane bound structure that stores food water and minerals?
A fluid-filled, membrane-bound structure that stores food, water, and minerals is known as a vacuole. In plant cells, vacuoles play a crucial role in maintaining turgor pressure, which helps support the cell structure. They also store nutrients and waste products, contributing to the overall health and functionality of the cell. In some cases, vacuoles can contain enzymes that aid in breaking down complex molecules.
What is the thin structure that surrounds a cell known as?
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.
This is a membrane-bound disk-shaped compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.?
The structure you're describing is called a thylakoid. Thylakoids are membrane-bound compartments within chloroplasts and cyanobacteria that contain chlorophyll and other pigments essential for capturing light energy. During the light-dependent reactions of photosynthesis, these structures convert light energy into chemical energy in the form of ATP and NADPH. Thylakoids are often stacked in structures known as grana, enhancing their efficiency in energy capture.
What structure houses a eukaryotic cell's DNA?
The structure that house a eukaryotic cells DNA is known as the nucleus. The nucleus has a membrane that is similar to a cell membrane.
What is the disc like structure inside this organelle called?
The disc-like structure inside the organelle is called a thylakoid. Thylakoids are membrane-bound compartments within chloroplasts where the light-dependent reactions of photosynthesis take place. They are organized into stacks known as grana.
Which structure regulates passage of molecules into and out of cells?
The cell membrane, also known as the plasma membrane, regulates the passage of molecules into and out of cells. It acts as a selectively permeable barrier, allowing some substances to pass through while blocking others to maintain the cell's internal environment.
What are membrane-bound spaces sacs surrounded by the membrane?
Membrane-bound spaces are sacs surrounded by a membrane that are known as vesicles. Vesicles are involved in various cellular processes, including transporting molecules within the cell, and interacting with other organelles.
What is the cell that lacks true nucleus and organelles?
The cell that lacks a true nucleus and organelles is known as a prokaryotic cell. Prokaryotes, which include bacteria and archaea, have a simpler structure compared to eukaryotic cells. Their genetic material is not enclosed within a membrane-bound nucleus, and they typically lack membrane-bound organelles. Instead, their cellular processes occur within the cytoplasm or are associated with the cell membrane.
What is pokaryotic also known as?
It means having cells that lack membrane-bound nuclei.
What is a fluid filled membrane bound structure that stores food water and minerals?
A fluid-filled, membrane-bound structure that stores food, water, and minerals is known as a vacuole. In plant cells, vacuoles play a crucial role in maintaining turgor pressure, which helps support the cell structure. They also store nutrients and waste products, contributing to the overall health and functionality of the cell. In some cases, vacuoles can contain enzymes that aid in breaking down complex molecules.
What is prokryote?
A prokaryote is a type of single-celled organism that lacks a membrane-bound nucleus and other organelles. Prokaryotes include bacteria and archaea, and have a simpler cell structure compared to eukaryotic cells. They are known for their ability to adapt to various environments and play important roles in ecological processes.
What purpose does Thylakoid serve?
Thylakoid is a membrane-bound compartment inside cells known as chloroplasts and cyanobacteria. Thylakoid serve to facilitate the light-depended reactions of photosynthesis. They convert light and glucose to energy.
What cell has no nucleus and no membrane bound organelles?
bateria cells, otherwise known as prokaryotic cells.
Are vacuoles membrane bound?
Yes, vacuoles are membrane-bound organelles found in the cells of plants and some protists. They are surrounded by a membrane, known as the tonoplast, that separates the contents of the vacuole from the cytoplasm of the cell. Vacuoles play various roles in the cell, such as storing nutrients, maintaining turgor pressure, and regulating cell expansion.
Name the structure at the edge of cytoplasm of the epithelial cells taken from your inner cheek?

What is the thin structure that surrounds a cell known as?
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.
