Which part gives plant cells strong support?

The cell wall provides structural support and protection to plant cells.

Ribosomal RNA is made by?

The nucleolus is responsible for producing ribosomal RNA (rRNA) and assembling ribosomes.

Main role of cell membrane is?

The cell membrane acts as a selective barrier, controlling the movement of substances in and out of the cell.

Which cells don’t have a nucleus?

Prokaryotic cells, such as bacteria, lack a nucleus and other membrane-bound organelles.

Cellular respiration happens in?

Mitochondria are the site of cellular respiration, where glucose is converted into ATP.

Main job of smooth Endoplasmic reticulum is?

The smooth endoplasmic reticulum is involved in lipid synthesis and detoxification.

Which RNA takes code from DNA to ribosomes?

Messenger RNA (mRNA) carries genetic information from DNA to the ribosomes for protein synthesis.

ATP is made in which organelle?

Mitochondria produce ATP through cellular respiration.

Plant cell protection comes from?

The cell wall provides rigidity and protection to plant cells.

Which organelle stores and edits proteins?

The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery.

Role of mRNA in cells?

mRNA carries genetic information from DNA to the ribosomes for protein synthesis.

Which part holds chlorophyll for photosynthesis?

Chloroplasts contain chlorophyll and are the site of photosynthesis.

Which Endoplasmic reticulum (ER) helps make proteins?

The rough endoplasmic reticulum is studded with ribosomes and is involved in protein synthesis.

Which part stores water and waste in plant cells?

The vacuole stores water, nutrients, and waste products in plant cells.

Structures that hold genes in the nucleus are?

Chromosomes contain the genetic material (DNA) and are located in the nucleus.

The outer layer in plant cells is?

The cell wall is the rigid outer layer of plant cells, providing structure and protection.

Liquid part of cytoplasm is called?

Cytosol is the liquid component of the cytoplasm, where many metabolic processes occur.

Organelles float in which part of the cell?

Organelles are suspended in the cytoplasm, which fills the cell.

Cells make energy from glucose using?

Cellular respiration converts glucose into ATP, the cell's energy currency.

Which part divides during mitosis?

During mitosis, the nucleus divides to ensure each new cell receives a complete set of chromosomes.

Transport in and out of nucleus is through?

Nuclear pores regulate the transport of molecules between the nucleus and the cytoplasm.

Site of protein folding and transport is?

The rough endoplasmic reticulum is involved in protein folding and transport.

Which structure helps in cell division in animals?

Centrioles play a key role in organizing the microtubules during animal cell division.

The jelly-like substance inside cells is?

Cytosol is the fluid component of the cytoplasm, where many cellular processes occur.

Small hair-like structures for movement are?

Cilia are small, hair-like structures that help in cell movement and fluid transport.

Which organelle helps plants make food?

Chloroplasts are the site of photosynthesis, where plants make their food.

Process of cell eating solid particles is?

Phagocytosis is the process by which a cell engulfs and digests solid particles.

Water moves across membrane by?

Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to high solute concentration.

The liquid inside the nucleus is?

Nucleoplasm is the semi-fluid substance inside the nucleus, where chromosomes and nucleoli are suspended.

A group of similar cells is called?

A tissue is a group of similar cells that work together to perform a specific function.

Which cells have no cell wall?

Animal cells lack a cell wall, unlike plant cells and bacteria.

Control center of the cell is?

The nucleus acts as the control center of the cell, regulating gene expression and cellular activities.

Movement of molecules without energy is?

Passive transport is the movement of molecules across a membrane without the use of energy.

Which organelle breaks down old cell parts?

Lysosomes contain enzymes that break down old or damaged cell parts.

Structure linking sister chromatids is?

The centromere is the region that links sister chromatids during cell division.

Basic building blocks of proteins are?

Amino acids are the basic units that make up proteins.

Mitochondria produce energy in the form of?

Mitochondria produce ATP, the main energy currency of the cell.

Cells with true nucleus are called?

Eukaryotic cells have a true nucleus and membrane-bound organelles.

Which of these can reproduce without a host?

Bacteria are free-living organisms that can reproduce independently, unlike viruses, prions, and viroids.
