- Front
- Back
|
-OSCILLATORIA, blue green algae -long chains of similar looking cells with no differentiation-no nuclei or chloroplasts -cyanobacteria, non eukaryotic, not a plant |
|
|
-Spirogyra
-Photosynthetic Eukaryotes -identify the chloroplasts -many are unicellular but some are multicellular -only differentiated cells are their reproductive cells |
|
|
-lack complex vascular organization
-no epidermis, cuticle or stomata -all the cells are lined with chloroplasts -empty space in the middle of each leaf is the vacuole which is largest feature of most plant cells -most of the nuclei are not visible |
|
|
-Anabaena
-cyanobacteria specimen |
|
|
Moss Young Gametophyte
-starts out as a haploid spore -consists of just a few dozen cells -gametophyte is young haploid multicellular plant that produces gametes by mitosis |
|
|
Moss
-Antheridial heads form at the tips of male gametophytes and produce sperm -Archegonial heads form at the tips of female gametophytes and produce eggs -Capsule forms at the tip of each sporophyte, is the diploid sporophyte & some cells undergo meiosis to make haploid spores |

Monocot Leaf vs. Dicot Leaf
|
|
|
Monocot Leaf
|
|
|
Zea Leaf (corn leaf)
-Monocot -parallel veins (means all the veins are cut straight across) -Vascular bundles are surrounded by bundle sheath cells |
|
|
Syringa Leaf (Lilac)
-epidermis -stoma -mesophyll: the middle tissue that fills most of the cell's volume, filled with chloroplasts that are the little red dots -mesophyll cells are surrounded by air spaces that allow circulation for gas exchange -vascular bundles with xylem and phloem |
