Specialized Cells
2 systems that vascular plants contain.
What is a root and shoot system?
This plant tissue is responsible for producing new cells through mitosis and allows plants to grow throughout their lives.
What is meristematic tissue?
This replaces the epidermis in older woody plants.
what is periderm?
This vascular tissue distributes sugars (nutrients) produced during photosynthesis and can transport materials up and down the plant.
What is phloem?
Specialized cells which are responsible for photosynthesis and form the majority of cells within the plant.
What are parenchyma cells?
These are areas of rapidly dividing cells formed by meristematic tissue.
What are meristems?
The name of pairs of cells that together form stomata.
What are guard cells?
These phloem cells are lengthy, end-to-end, contain sieve plates, and lack a nucleus when mature.
What are sieve tube elements?
String-like fibre in celery is a result of this specialized cell.
What are collenchyma cells?
This type of growth increases the length of roots and stems and occurs at apical and intercalary meristems.
What is primary growth?
The name of very small epidermal extensions found in roots.
What are root hairs?
These phloem cells have a nucleus that controls and supports sieve tube elements.
What are companion cells?
The difference between sclereids and fibres.
Why are sclereids disturbed randomly + have an uneven shape and fibres are needle-like and form elastic-like tissue when staked end to end?
This type of growth increases the width (girth) of roots and stems and occurs in woody plants.
What is secondary growth?
three cell types that are found in ground tissue.
What are parenchyma, collenchyma, and sclerenchyma cells?
This is an important feature of phloem transport, allowing sugars to get to both growing tissues and storage organs.
What is bidirectional (up and down) transport?
