The main difference between photosynthesis and respiration is that photosynthesis occurs during the day, and breathing occurs during the day and at night. Leaves (and other active metabolic tissues) breathe at night. They use oxygen to release carbon dioxide. Low intensity at dawn and dusk. Therefore, the photosynthesis rate and respiratory rate become equal in …

The nucleus is a membrane-bound organ that contains the genetic material (DNA) of eukaryotes. In this way, it maintains cell integrity by facilitating transcription and replication processes. It is the largest organelle of the cell, accounting for about one-tenth of the entire cell volume. This makes it one of the most easily identified organisms under …

Saci Enzyme are biological catalysts. The main feature of enzymes is that they have biologically active proteins that can accelerate chemical reactions in cells, but they will not alter the reactions. As proteins, they are always bound in chains of amino acids with specific shapes and bonds. Enzymes can increase the efficiency of biological reactions. …

In the nucleus of each cell, DNA molecules are packed into linear structures called chromosomes. Each chromosome is made up of DNA that is tightly wound several times around a protein called histone that supports its structure. When the cell is not dividing, even under the microscope, the chromosomes do not appear in the nucleus. …
