Answer: The correct answer is Vacuole
Explanation:
The vacuole is an organelle found in the central portion of plant cells, and is usually filled with cell sap that acts as a "store house" for many substances entering into the cell.
Therefore, the herbicide waste absorbed by the plants will be stored in the VACUOLE.
Vacuole in the plant will most likely store the absorbed herbicide waste.
Vacuole is an important site for the degradation of cellular lipids, membrane-associated proteins, and cytoplasmic proteins
What is Vacuole?
Vacuoles are organelles of plant, fungal, and algal cells. They are part of the internal membrane system and are separated from the rest of the cytoplasm by a membrane called the tonoplast .
The term “vacuole” means “empty space”. They help in the storage and disposal of various substances. They can store food or other nutrients required by a cell to survive. They also store waste products and prevent the entire cell from contamination.
The vacuoles in plant cells are larger than those in the animal cells and occupies more than 80% of the volume of the cell. It may be single or more in number.
Structure:
A vacuole is a membrane bound structure found in the cytoplasmic matrix of a cell.
The components of the vacuole, known as the cell sap, differ from that of the surrounding cytoplasm.
The membranes are composed of phospholipids and are embedded with proteins helping in transporting molecules across the membrane. Different combinations of these proteins help the vacuoles to hold different materials.
Vacuoles perform three specific types of functions:
- Storage:
It stores salts, minerals, pigments and proteins within the cells. The vacuole is also filled with protons from the cytosol helping in maintaining an acidic environment within the cell and a large number of lipids are also stored within the vacuoles.
- Turgor Pressure:
Vacuoles are filled with water exerting pressure on the cell wall called as Turgor Pressure providing shape and helping to withstand extreme conditions.
- Endocytosis and Exocytosis:
Substance entering through the vacuole is called as endocytosis and excreted through Exocytosis.
Vacuoles play crucial roles in
- cell expansion
- function as lytic organelles that contain digestive enzymes
Compounds contained within vacuoles also protect cells against environmental damage and deter attack by herbivores .
What are the other Cell Organelles?
Ribosomes:
A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during a process called protein synthesis or translation.
Ribosomes also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA.
Chloroplast:
It is a cell organelle comes under the category of Plastids which are exclusively present in Plant cells.
These plastids are double-membraned cell organelles which play a primary role in the manufacturing and storing of food.
Types of plastids –
Chromoplasts- They are the color plastids, found in all flowers, fruits and are mainly responsible for their distinctive colors.
Chloroplasts- They are green coloured plastids, which comprise green-coloured pigments within the plant cell and are called chlorophyll.
Leucoplasts- They are colorless plastids and are mainly used for the storage of starch, lipids and proteins within the plant cell.
Mitochondrion:
Mitochondria are membrane-bound cell organelles that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Thus it is also called as power house of the cell.
