Ground tissue Flashcards
(22 cards)
What are the functions of parenchyma?
Storage, support,
photosynthesis
What are the role of Collenchyma?
Strength, flexibility
What are the functions of Sclerenchyma?
Additional strength
and protection
What is the shape of parenchyma cells?
Round, oval, or elongated.
Are parenchyma cells living or non-living?
Living.
What type of cell wall do parenchyma cells have?
Thin and flexible primary cell wall made of cellulose and piten.
What is found between parenchyma cells that helps with gas exchange?
Large intercellular spaces.
What are the main contents inside a parenchyma cell?
Dense cytoplasm, large central vacuole, and prominent nucleus.
How are parenchyma cells arranged in tissues?
Loosely packed, forming a soft and spongy structure.
Name three functions of parenchyma cells.
Storage, photosynthesis (if they contain chloroplasts), and support.
What is parenchyma called when it contains chloroplasts?
Chlorenchyma.
What is the function of collenchyma cells having unevenly thickened cell walls with cellulose and pectin?
To provide flexible support to growing parts of the plant without restricting growth.
What is the function of collenchyma cells being elongated and arranged in strands or cylinders?
To give lengthwise support to stems and leaves, especially in young, growing regions.
What is the function of collenchyma cells being alive with a nucleus and cytoplasm?
To allow for growth, metabolism, and continued support during the plant’s development.
What is the function of collenchyma cells having no lignin in their walls?
To ensure the cells remain flexible and stretchable, allowing the plant to bend without damage.
What is the function of collenchyma being located just beneath the epidermis in stems and petioles?
To provide support to the outer parts of the plant while maintaining elasticity for movement and growth.
What is the function of collenchyma cells containing protoplasm?
To participate in the transport and storage of nutrients and other substances.
