Muscle cells have an abundant, modified smooth ER called the sarcoplasmic reticulum.

The release and reuptake of Ca2+ by the sarcoplasmic reticulum trigger myofibril contraction and relaxation, respectively

Number of carpels are variable

If only one carpel exists within an ovary, it is said to be monocarpous or monocarpellary Ex;  Fabaceae

Number of carpels are variable

There may be more than one carpel, or two carpel called Bicarpellary they may be free and, if so, are said to be apocarpous. Ex- as in lotus and rose

Number of carpels are variable

There may be more than one carpel, or two carpel called bicarpellary they are termed syncarpous when carpels are fused. Ex-  as in mustard and tomato (brassicaceae and solanaceae)

Number of carpels are variable

There may be 3 fused carpel are termed tricarpellary syncarpousEx- lilliaceae
