Two specialised types of parenchyma are chlorenchyma and aerenchyma. The apical meristems and the reproductive cells are parenchymatous. Types of parenchyma: Assimilatory: parenchyma cells which take part in photosynthesis contain chloroplasts and form a tissue called Chlorenchyma. Plasmodesmata connections occur between the cells through pits in the walls Parenchyma cells may store reserve materials. Solution: Apical meristem is present at the growing tips of stems and roots.

Q2. Companion cells are absent in pteridophytes and gymnosperms. The cells have many spiny projections. They function in storage, photosynthesis, and as the bulk of ground and vascular tissues. Q1. Simple Permanent Tissues : These tissues are made up of cells which are structurally and functionally similar. Type of parenchyma which contains chlorophyll and can perform photosynthesis, is called chlorenchyma. Vascular Parenchyma: The parenchyma cells which are associated with vascular tissues.

Simple tissues are homogeneous and composed of … Infraxylary: This type of collenchyma tissue encircles the vascular bundle towards the xylem side. Chlorenchyma takes part in photosynthesis. The ability of plant tissues to be repaired after an injury depends partially on parenchymatic cells. They consists of relatively unspecialised cells with thin cell walls. Vascular system is an example of tissue system. 9 years ago. These cells may be of one type or different types.
