Cell Division and Plant Tissues Biology Quiz

Cell Division

• Interphase is the stage where DNA replication occurs, ensuring that each new cell receives a complete copy of the genetic material.
• During prophase, chromosomes condense, making them more visible, and the nuclear envelope breaks down, allowing the chromosomes to move towards the center of the cell.
• Metaphase is characterized by the alignment of chromosomes at the metaphase plate, ensuring that each daughter cell receives a complete set of chromosomes.
• Anaphase involves the separation of sister chromatids, which move towards opposite poles, resulting in each daughter cell receiving a complete set of chromosomes.
• Telophase is the stage where chromosomes decondense, and the nuclear envelope reforms, re-establishing the nuclear structure.
• Cytokinesis is the final stage of cell division, where the cytoplasm divides, and the cell splits into two daughter cells.

Plant Tissues

• The dermal tissue is the outermost layer of the plant, providing protection against water loss and regulating gas exchange.
• Ground tissue makes up the bulk of the plant body, performing various functions, including storage, photosynthesis, and support.
• Vascular tissue is responsible for conducting water, nutrients, and sugars throughout the plant, comprising xylem and phloem.

DNA

• DNA is a molecule that carries genetic instructions for the development, functioning, growth, and reproduction of all known organisms.
• It is a vital component of cells, providing the genetic blueprint for life.

Differences between Xylem and Phloem

• Xylem is responsible for transporting water and minerals from roots to shoots, providing structural support to the plant.
• Phloem transports sugars and other organic molecules from leaves to roots, fruits, and other non-photosynthetic parts, ensuring the distribution of nutrients.

Pathway of Food Through the Heart and Body

• The pathway of food through the digestive system begins in the mouth, where food is chewed and mixed with saliva.
• Food then passes through the esophagus, entering the stomach, where it undergoes acidic digestion.
• The partially digested food enters the small intestine, where most of the nutrient absorption occurs.
• The remaining waste products enter the large intestine, where water is absorbed, and the feces are formed.
• Finally, the waste is eliminated from the body through the anus.

Pathway of Food into the Mouth Until Excretion

• Food enters the mouth, where it is chewed and mixed with saliva, beginning the digestion process.
• The food is then swallowed, passing through the esophagus, into the stomach, where acidic digestion occurs.
• The partially digested food enters the small intestine, where most of the nutrient absorption takes place.
• The remaining waste products enter the large intestine, where water is absorbed, and the feces are formed.
• The waste is finally eliminated from the body through the anus.
