Solved
Meristem cells/tissues - ✔✔First cells when a plant embryo begins to
develop; cells organize themselves into tissues
Apical meristems - ✔✔Tissues located at the ends of a plant; have 3 types
of specialized tissues: epidermal, ground, vascular
Epidermal, ground, vascular - ✔✔3 types of apical meristems
Epidermal tissue - ✔✔forms the outer protective covering of a plant; cells
exposed to air are covered by a waxy cuticle, restricting water loss and
resists attacks from microorganisms.
Ground tissues - ✔✔Fills the interior of a plant and helps carry out the
functions of a particular organ; includes 3 types of simple tissues:
parenchyma cells, collenchyma cells, sclerenchyma cells
Parenchyma cells - ✔✔Type of simple ground tissue; has thin walls, are
active in photosynthesis and storage.
, collenchyma cells - ✔✔Type of simple ground tissue; provides support for
primary tissues, has irregularly shaped corners and thicker cell walls.
sclerenchyma cells - ✔✔Type of simple ground tissue; fibrous cells that
give stalks their gravity-resisting strength.
Vascular tissue - ✔✔Tissue that extends from the root through the stem to
the leaves, and vice versa; 2 types of vascular tissues: xylem and phloem.
Xylem and Phloem - ✔✔2 types of vascular tissue in vascular plants
Xylem - ✔✔Type of vascular tissue in plants; transports water and minerals
from roots to leaves; contains two types of conducting cells: vessel
elements and tracheids.
vessel elements and tracheids - ✔✔Two types of conducting cells in Xylem;
dead at maturity, cell walls interconnect to form pipelines for water flow.
Phloem - ✔✔Type of vascular tissue in plants; transports sugar, in the form
of sucrose, and other organic compounds such as hormones, often from
leaves to roots; conducting cells are called sieve-tube members and have a
cluster of pores in their end walls collectively known as a sieve plate.
sieve tube members - ✔✔The conducting cells of phloem; collectively
known as a sieve plate; each one has a companion cell.
