\.characteristics of land plants
multicellular, almost all are terrestrial and immobile, haploid and diploid adult life stages
\.not all plants....
have roots
have leaves
produce flowers, fruit, or seeds
have pipes (vascular tissue)
\.types of plants
vascular and nonvascular, gymnosperms and angiosperms
\.key characteristics that distinguish different groups
vascular tissue, seeds, fruits, and flowers
\.why are roots covered in thousands of very tiny root hairs?
increases the amount of water and nutrients the plant can absorb from the soil.
\.shoot system
stems and leaves; photosynthetic
\.node
the place where the leaf attaches to the stem
\.roots
water and mineral uptake, anchors plants tot the ground, storage of photosynthetic products as
starch
\.three categories of plant tissue
, dermal - protective 'skin'
vascular - transport
ground tissue - photosynthesis, storage, and support
\.plants form gametes by
mitosis, making exact copies of the cell ("xeroxing")
\.what types of nutrients or resources do you think plants need to survive?
nutrients from soil (nitrogen, potassium, and phosphorus), air, light, calcium, and water
\.apical
towards the apex
\.a potato plant uses photosynthesis to create sugars from carbon dioxide and transports this
sugar to the potato root where the sugar is attached in long chains of carbohydrate called
________ for storage
starch
\.xylem
vascular tissue that carries water upward from the roots to every part of a plant, ridgid, dead
cells, structural support, tubular
\.phloem
the vascular tissue in plants that conducts sugars and other metabolic products downward from
the leaves.
\.stomata
the small openings on the bottom of leaves through which oxygen and carbon dioxide can move
\.guard cells
immortal cells, plant stem cells, can divide to produce any new cells. totipotent
\.meristem
immortal cells that can produce any type of plant tissue (the plant "stem cells")
\,we use a wide variety of plant-derived chemicals (phytochemicals) for medical purposes. In
some cases, different cultures and families have herbal remedies for illnesses. What are some
of the plant-based treatments that you may have heard of in the media or from family and
friends?
