Cell Biology
-
Striated muscle fibres:
-
Consequently, they have multiple nuclei despite being surrounded by a single, continuous plasma membrane
-
Aseptate fungal hyphae:
Fungi may have filamentous structures called hyphae, which are separated into cells by internal walls called septa
Some fungi are not partitioned by septa and so they have a continuous cytoplasm along the length of the hyphae

-
Functions of life
Unicellular organisms (e.g. Euglena, amoeba) are the smallest organisms capable of independent life
-
Paramecium
-
-
-
Solid wastes are removed via an anal pore, while liquid wastes are pumped out via contractile vacoules (excretion)
-
Paramecia divide asexually (fission) although horizontal gene transfer can occur via conjugation (reproduction)
Scenedesmus
-
-
Daughter cells form as non-motile autospores via the internal asexual division of the parent cell (reproduction)
