Tissue Lab

Purpose To observe the cells that make up 4 different tissues
Observation
See attached diagrams of the Human Blood Smear, Giant Multipolar Neurons Smear, Monocot & Dicot Stem and Monocot & Dicot Leaves.
Analysis
Red blood cells are unique in their shape and are designed for a specific task that is aided by their form. Red blood cells are small in their shape so they can go into the smallest capillaries in places like the fingertips so they don’t get stuck and restrict blood flow. Red blood cells are red because the hemoglobin, a substance that traps and carries oxygen, gives it that red pigment. Furthermore, red blood cells are free of a nucleus and have a bi-concave shape which allows for more surface area for the hemoglobin to come into contact with the oxygen outside the cell. Red blood cells are what carry oxygen from our lungs to our brains and are very important for us. Without the special qualities that red blood cells have, the tasks of the tissue would be very difficult.
Giant Neurons are unique in their shape and are designed for a specific task that is aided by their forms. There are many dendrites and they’re spread apart so they can pick up stimuli from every point of the body. However, there is usually only one axon that is long so the cell can send information to places in the body that are further away. The neuron cells themselves are long and thin to transmit information and nerve impulses for long distances. Neurons are what transmit information to and from the brain to carry out functions of our daily lives. Without the special qualities a neuron has, it would be difficult for the cell to carry out its functions the way it does.
The epidermal cells in leaves are special in the sense that they are designed specifically for a certain task which is assisted by its form. The epidermal cells form a boundary between the plant and the outside to protect it from any foreign and unwanted objects, the cells are tightly packed together to minimize water loss and maximize protection from the outside. There are pores on the cells called stomata and they are what allow CO2, water vapor and O2 to…
