I want to learn penetration testing on kali linux platform, for that I found that the wifi card is needed. But my question is that, if I install the kali linux as main operating system or make separate partition for kali linux and windows, than also wifi card is needed or not?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
First of all, if you don't want to perform wireless attacks (sniffing, cracking, impersonating an AP,...) you don't need a Wi-Fi card, any kind of NIC will be enough.
For wireless attacks, you clearly need a wireless NIC. This can either be internal, i.e. built-in, or external, i.e. a USB adapter or a PCI Wi-Fi card. Note that if you already have a built-in wireless card supporting promiscuous mode and packet injection you don't need an additional card.
A good list of Wi-Fi cards supported by the Aircrack suite - which is included in Kali as a tool for Wi-Fi attacks - can be found on their own website: http://www.aircrack-ng.org/doku.php?id=compatibility_drivers&DokuWiki=esblrp5ctfa9d7u2qbpmamndp5#which_is_the_best_card_to_buy.
