Meristematic and Permament tissues
What characterizes meristematic cells?
They actively divide and are undifferentiated.
The outer layer that protects the plant.
What is the epidermis?
Tissue that does photosynthesis and stores food.
What is parenchyma?
It is the vascular tissue that transports water and minerals from the roots to the stem and leaves.
What is xylem?
What are secretory tissues?
Tissues that produce and release substances
Where is the apical meristem located?
At root and shoot tips.
A layer that helps prevent water loss.
What is the cuticle?
Tissue that supports young plant parts.
What is collenchyma?
It is the tissue responsible for transporting organic substances produced during photosynthesis from the leaves to other parts of the plant.
What is phloem?
What substances can secretory tissues produce?
Nectar, resin, oils, or latex.
What growth does the lateral meristem produce?
Secondary growth (thickness).
Small openings on leaves for gas exchange.
What are stomata?
Strong tissue that gives hard support.
What is sclerenchyma?
These are the two types of conducting cells in the xylem; one is wider and shorter, and the other is longer and narrower.
What are tracheae and tracheids?
Where are secretory tissues usually found?
In leaves, stems, and flowers.
What defines permanent tissue cells?
They are differentiated and stop dividing.
Cells that open and close the stomata.
What are guard cells?
Inner part of the leaf where most photosynthesis happens.
What is mesophyll?
Perforated structures formed between phloem cells that allow the passage of elaborated sap from one cell to another.
What are sieve plates?
What is the function of nectaries?
They produce nectar to attract pollinators.
Why do permanent tissues depend on meristems?
They originate from them.
The outer tissue that replaces the epidermis in trees.
What is the periderm?
Root layer that controls water entering the plant.
What is the endodermis?
It is the structure formed by the union of xylem and phloem that, in addition to transporting substances, also provides support to the plant.
What is a vascular bundle?
Why are secretory tissues important for plant survival?
They protect the plant and help in reproduction
