Is it necessary that collenchyma has a cytoplasm ?

collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage. The stretchy properties of the strands of celery are due to collenchyma tissue. Collenchyma tissue is found immediately under the epidermis, young stems, petioles, and leaf veins. Also, it has been seen in avocado fruit hypodermis. Collenchyma cells may or may not contain a few chloroplasts, and may perform photosynthesis and store food.

Explanation:

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
